Two whole console generations? No, the G27 came out in 2010, so it was supported for half of one console generation. The PS4 doesn't use a "different ffb protocol" than anything else, otherwise other legacy wheels wouldn't work either, and in case you didn't know, the G29 uses the same FFB as the G25/27, the only difference is it has hardware that allows it to be recognised by the console like a DS4 is, to work in all menus.
Sony haven't stopped any company from providing drivers to devs for their peripherals to work in games, and both Thrustmaster and Fanatec have provided drivers to multiple devs to support their wheels. All of this is common knowledge, so I don't know how you think Logitech had no say in whether their wheels would be supported or not lol.
Logitech have done this to try and swindle their customers out of more money, and it's hilarious how many people are buying their new wheel, as it's just a G27 with a new rim on it that has the DFGT buttons on it. That's the reason they're not supporting the 25 and 27, because, unlike their competition, they haven't advanced their wheels in a decade, so the latest one offers nothing new for the inflated price. Both Thrustmaster and Fanatec support their old wheels on the current consoles, but also sell fully compatible new wheels for people wanting to upgrade, that are genuinely better than their legacy wheels.
But hey, don't let the truth get in the way of a good story
Hahaha. I won't.
First, the G27 isn't even a PlayStation wheel. It's a PC wheel. Worked on PlayStation tho. Pretty nice, huh?
Oh, and the GT Force for GT3 (Early PS2, 2001/2002) as well as the Driving Force for PS2, and Driving Force Pro were ALL still supported in GT6, a LATE PS3 release... alongside the DFGT, the T500RS... and oh yeah, the UNLICENSED G25 and G27. So that's... damn near two whole generations! Wow.
What's the problem man? Why can't people see that Sony and Logitech NEED to make money too, or they can't bring us the games and accessories we want?? I mean, I hate replacing gear as much as the next guy, but when you change consoles, you usually need new accessories (unless they're Logitech wheels, amirite guys??)
Do I think the "G29" is a good deal? Hell no. But I understand WHY they had to do it. And I am sure that if Logitech didn't have to make a "new" wheel they would happily just still be selling G27s and laughing all the way to the bank paying no licensing fees.
Thrustmaster paid for a new license BTW, and no one has promised T500 owners (and I am one) universal compatibility.
Fanatec snuck in the back door on TWO games, PCARS and F1 2015, so far anyways. Not exactly full compatibility. BTW, I also have a Fanatec CSR Elite wheel too, so I'd SURE like to see it work on PS4.
So as you might see, I don't think it's fair to vilify Logitech for giving us WAY more support than practically any other company has. You don't like it, hey, good for you. Build an adapter, use your G27, I don't even blame you. Just, you know, don't be a dick about it.
Anyways, I've said my bit, and you've all said yours. Haters gonna hate, right, one way or another.
