This isn't to say I wouldn't want to play GT6 on PS4, but if they can release this thing on PS3 then go right ahead. Those few saying GT5 pushed limits on PS3 WAHHHHHHH!!!! Go play Batman Arkham City and even Uncharted 2 or 3, or Gow of War 3 you'd convince me those games pushed the PS3 to it's limits WAYY MORE than GT5 ever did.
Just because of that part...You don´t play on PC.
Compare Batman Arkham City with the PS3 version and there is a huge difference.
I tried the demos of both Batman games and I bought both versions on PC.
PS3 exclusives looks good yes but still you forget that those games are running at 30FPS and only 720p.
The day you see games running at 1080p, 60+FPS with better textures and details overall...most of multi-platform games in resume...You´ll understand why most of us want GT6 on the PS4.
Also you forget about other stuff...but having better hardware we can have more cars on track, not just better graphics.
The question is, Do you want to play GT5 again but with other name and same limitations or a true far better experience?
I know some people think that the game just needs more features but you can´t make a sequel being or looking the same as the previous game...because that´s what happens if GT6 will be released on the PS3.
Don´t think with the money...think in possibilities.
If the PS4 comes out at the end of the year, you can start to save money for it and for GT6. It won´t be that hard to do it.
