Assuming the PS4 sells similar to the PS3,
Let me stop you on that assumption alone. There has been no indication that the cost of the PS4 console, will be anywhere near the original cost of either of the PS3 consoles, even prior to inflation calculations, it is likely the PS4 will be cheaper "not because of a source" but because of common sense, they've announced no super expensive technologies in this console, and they would prefer to make the console as price competitve as possible to make it sell.
there won't be any launch consoles left regardless of a GT title or not. As Scaff alluded to earlier, launch consoles tend to sell out. Why waste GT6 on a smaller, already satisfied audience?
There's this concept, it might interest you, it's called longevity, you see, when they release a new game on a new console, the new console tends to sell better 'beyond' its initial launch interest. Sure, the first couple of batches of consoles will sell quick, but what then? Drive Club is going to make us all forget our PS3 and GT5? Is that really the angle you're going with here? Oh wait you didn't say that never mind, I'll stop drawing my own conclusions, I have no idea what you meant beyond what you said.
As others have said anyway, there's no reason why 'company whoever' wouldn't initially release drive club, then within a year, PD release GT6.
My biggest gripe, is people pretending a PS4 GT7 is a sure thing, due to nothing with no confirmation from anyone else from either Sony or PD themselves, which is madness.
Funny, not that I said this at all, but you must be equally disappointed with people hoping for GT6 on PS3 then? Equally confirmed? No?
Well, if we think about it for a moment, its most likely GT7 will be a PS4 title, its even more likely than GT6 frankly, here's why I think so, not that I said its a sure thing as you seem to have read into... but its pretty much a sure thing imo for the following reasons.
1. Scenario A, PD release GT6 on PS3, GT7 may be a way away, but unless they entirely skip over the PS4 console or go bust, their next number after 6 is... 7. So what else are they going to do? Release it on PS3 or PS5?
2. Scenario B, PD wait and release GT6 on PS4. They've been working on this thing for 2-3 years now, assuming they start on GT7 shortly after GT6 is released, what are the chances of it being on PS4 instead of PS5? I would say the odds are on the PS4 here as well.
So despite accusing me of saying, virtually what I just said when I hadn't said it yet, it's not an illogical position at all now is it?
...if they put GT6 on PS3 they'll have to restart the whole thing again for GT7 on PS4, which is just so illogical...
While it makes the most sense for GT6 to be released with/soon after the PS4, I do hold the possibility that it'll be released on PS3, ...despite the fact [GT6 will] be cheaper for me to buy, ...I [therefore] won't buy a PS4 until GT7 then, which could be until 2018. [In Scenario A where GT6 is released on PS3, I have no incentive to purchase a PS4 until a new GT is on that console, afaik, considering I am primarily a PC gamer, and use my PS3 for virtually nothing other than GT5]
