GT5 is a huge game, but its also one with many, many flaws and a totally inconsistent level of quality. To such a degree that had it not been a GT title a good chance exists that it would have been given a much harder time at launch.
PD could resolve a lot of the issues with GT5 in a new title without even needing to go to the PS4.
True, but by no means certain. After all PD could have done so much better with a more powerful system than they did with GT3 and GT4, yet they didn't really move the series along a great deal at all, despite having more power in the PS3 than they even had with the PS2.
Its in the very first post in this thread, now while I can understand not reading it all, I would have hoped that at least the opening post would have been read by yourself.
Quite a few reasons, the main ones are however:
- GT5 cost $60 million (at least) to develop, GT5 sales only just cover that in terms of reough revenue return. It makes sense to maximise that investment wth another title on the same platform (which woudl then be able to share that development cost)
- The PS3 has 170 million potential buyers for a new GT title.
- A GT title needs to shift at least 5 million units in its release month to match past sales, that would require (at a 20% attach rate) 25 million PS4s to be on the market.
In short Sony and PD can make a good return by throwing another GT title at the PS3, particularly given that the user base for a PS4 GT title will not exist for a good 12 - 24 months from the launch of the PS4.
