I think Sony's development time is spot on, I don't time is it really a matter(don't get me wrong, it does) but it's a matter of resources and effort(RolStoppable basically said what I was going to say but better)
no game is going to be perfect and delaying it for more time can impact initial sales andreview scores (mainly GT5) no matter how long you work on a game it's destine to have flaws, I get what your saying;(or atleast I'm close) that these games could be better from the get-go, but hopefully it something that could be solved with a patch/dlc. and you wouldn't want development to get to costly(though I doubt Sony would care)
don't get me wrong, more time wouldn't hurt, also like you plan for the PS4, I could honestly see that hapenning.
