I'm pretty sure a large part of Fanatec's current market is PC, with only a small number of CSWv2 owners on Xbox One and an even smaller group on PlayStation (almost certain all of that group also own PCs). Since the CSWv2 is a great PC wheel and almost all sims are on PC, your advice makes no sense. Especially since PC sim racers in the market for a second hand CSWv2 are going to be totally oblivious to GTS for the most part...
The "sell now" argument is also rubbish. Knowing Thrustmaster, having watched their peripheral releases for the last 5+ years very carefully, I'd argue that the new GTS wheel is unlikely to be available except possibly in very small quantities in a few specific countries in 2016. It usually takes them up to 6 months from the actual physical launch of a new wheel before you can buy it widely. Something this expensive will probably be even smaller quantities and longer wait times.
Finally, Fanatec has just started teasing the new CSL wheel, and it's very likely that the CSL release and the promised PS4 license for Fanatec will happen at the same time.
In short, lots of reasons not to sell a CSWv2 and to wait for the full picture to appear before jumping at a new wheel.
Your reasoning is flawed. The PC sim racing community is well aware of the Thrustmaster wheel, news and discussion of this wheel has been on every site and the sim racing community is waiting to find more information out about it. No one cares that it is a GT wheel and an interest in GTS is not required to know about this wheel. It is a direct drive wheel, considering the current options for DD wheels range from above 1k for a DIY wheel up to 4k+ for the fully optioned Bodnar the news that Thrustmaster is bringing out a DD wheel is something everyone is interested in especially those who are not in the DD market price range but would like a DD wheel.
The advice is just as relevant to PC as it is Playstation as Thrustmaster wheels are not Playstation exclusive and plenty of people use them for PC. In fact looking at the iRacing forums in the entry to mid level price range the Thrustmaster wheels are currently the most recommended wheels. Currently DD wheels are also very popular and the DIY option has proven very popular. You can bet that a lot of PC sim racers are waiting to find out more.
As for what you said about the release of the Thrustmaster wheels, I've never witnessed that. In Australia I've never been able to walk into a store and buy Thrustmaster wheels but I have always been able to purchase them at launch through retailers, I just never have because of the premium prices the retailers have quoted me. But I have also followed these wheels like all the other wheels, reading all the reviews and so on. And if there were shortages in a certain area that I am unaware of these must have been geographical shortages because I have been unaware of these and always been able to find an abundance of reviews.
Finally the promised PS4 wheel from Fanatec. This is the first real PS4 wheel from Fanatec. Fanatec did the wrong thing in the past by saying their prior wheels were PS4 wheels and have been asked by Sony to stop promoting those wheels as being Playstation compatible which they have complied with. Fanatec are finally taking steps to have a licensed wheel and you can be sure that wheel will be fully compatible on the PS4.
People can sell or keep as they choose. If I owned Fanatec right now I'd sell.
Wait, so the guy who bought the last 3 Logitech wheels is defending Logitech's latest wheel? Well I'm shocked. I mean, it's not like it's in your best interests to defend your decision to keep forking out hundreds upon hundreds of dollars for wheels that are only marginally better than the ones you already had. Also, how are your kids' opinions on racing wheels any more relevant than your own biased opinion? They obviously would only know what you have told them, and considering what you keep harping on about here, it's pretty obvious what you would have told them.
I never defend my purchasing decisions if they don't warrant it and I've said negative things about plenty of things I have purchased over the years. Here's a fact for you, I'm an original Ioni Pro supporter and now will probably sell that in anticipation of the Thrustmaster wheel. You would also not be aware that I have many times suggested that people might be better off purchasing a Thrustmaster wheel over the Logitech wheel in regions where the Logitech wheel prices are comparable to the Thrustmaster prices. It just happens that where I live the Logitech wheels are much better value, mine was less than half the price of a comparable Thrustmaster wheel and I was able to pick it up from a local store at that price. And my kids have no problem letting me know when they disagree with me, my kids like the G29 because it is better than their Logitech wheels. It isn't a biased opinion, they always tell me "Dad you should swap wheels with me" or "Dad you should buy a new wheel so I can have your wheel". I'll say that if I wasn't able to purchase my G29 for the price I did I would have bought a T300 instead with T3PA pedals instead. I'll say I'm looking forward to the Thrustmaster DD wheel and will most likely buy one at some point in the future and if it is great I will say so and if it is a dud I will say so. I've written negative things about the G29 as well. Like previous wheels it still has the dead zone issues of previous wheels, this is the single worst thing about all Logitech wheels. Also I have written that even though the brake is a great improvement over the previous pedals the pedal is too long before it hits the rubber and then pedal range is also cut off, the brake could have easily been much better than it is. I have written that without using the Thrustmaster T3PA pedals I suspect they are better than standard G29 pedals.
One thing you can be sure about with me is I never feel the need to defend my purchasing decisions. I have actually destroyed and dumped things I paid money for rather than selling them because I'd rather tell people I think they are rubbish and not sell that rubbish to someone else. I have a pair of these that I will not sell
http://www.sony.com.au/product/mdr-10rbt because they are rubbish. They sound great but the construction and quality is terrible. I haven't had a problem saying negative things about certain Apple products I have owned over the years and as a Apple fan right back from the 80's who has owned many many Apple products and loved them I have no problem saying I think the products Apple is currently bringing out are overpriced crap in my opinion and a sad sign of how far the company has fallen.
I own a Razer Naga mouse and I'll never buy another Razer mouse. I have no problem admitting I am a big fan of Ibanez guitars, I currently own 3 and have had others, I also have a custom guitar that is amazing and I have no problem saying my favourite guitar is my Dean which is one of the cheapest guitars I own.
As a guy who has spent well over $500 on iRacing over the years and possibly closer to $1000 I have no problem saying that I'm planning on letting my subscription expire this year with no regrets.
So don't believe what I have to say based on whatever reasoning you come up with. I don't care if you trust me or don't trust me but I'm about as unbiased as anyone can be and I bought my G29 knowing I could just take it back if I didn't like it and lose nothing. And I bought it with the intention of taking it back, I even warned the staff when I picked it up that I anticipated that I would be returning it. And my comments about it are only relating to comparing it to prior Logitech wheels because that is what all the fuss is about. People who think the G29 is not worth buying over previous Logitech wheels are talking rubbish and probably haven't tried them side by side, I have tried them side by side, the G29/G920 are the best wheels Logitech have ever made. A T300RS might be a better wheel, I think it probably is, I'd love to own one with T3PA pedals but a G29 cost me $275 and a T300 + T3PA would cost me over $600 plus postage. I am expecting to spend more than that to buy Thrustmasters new DD wheel which I currently believe I will buy.
