I think u re wrong about photorealism on GT5 ...
Car are perfectly modelised but it is the same on PGR4 for example.
And both will be killed by any console race game released on 2010 for example.
Dude, GT looks better than what you think it does. If a game looks as realistic as reality what will be more relistic in 2010 when the ps3 is reaching its true graphics?
The 360 has shown its potential through gears of war stated by epic.
