Well, that's the thing. We have waited so long, and then there's still major mistakes/things to be picky about. It should have been good firsttime round given the time it took them :P
Not related, but I think the same thing will happen with GT5. That game has been announced so many times, that now it MUST be PERFECT. Every slight little wrong thing will get major attention now, with the conclusion that GT sucks because of those little mistakes that will still be in the game.
That's how it works all time, so I think Stewart and guys/girls?? were prepared for these reactions anyway
