Playing devils advocate here, that's all very good amar212, but just think about it, what can GT5 do that so significantly transforms the racing game genre? At the end of the day, you are still acquiring cars and racing them around tracks, either offline or online. Online is nothing new to the genre, and we've already seen pretty much how the game will look. Sure, it may well end up the best looking racer we've seen to date, and may have fantastic physics/AI, as well as really detailed damage on certain cars. Even the interfaces that we've been shown to date are nothing particularly new.
Now, if they introduce that same level of tournament control that we've seen in GT Academy 2010, with those same screens etc., then that could represent a great leap forward for online racing at least for console games.
I guess it's just frustrating to have all that said about how the game is going to transform the genre, but have no evidence of it despite it being 90% complete. If they can pull it off and wow us all like he believes, fantastic, but I just get the feeling that despite all of this development time, we are "just" going to get a bigger, better looking, better sounding, more varied version of the franchise we know and love. I hope I'm wrong.
