I'm so glad I ditched Sony, and went with the 360 instead. I stayed with Sony for years..even paid a ridiculous amount to get one of the first PS2s. All I ever felt like I was doing was waiting for Gran Turismo...wait wait wait. Screw Sony, and Screw Polyphony. They don't care about you. Not one bit.
Not once have I ever felt like I was waiting for anything with the 360. Games come out on time, my system works great (knock on wood..no rings of death please), and it's the most fun I've had on a console since the Atari 2600.
GT5 looks great. But if it is never released, then what good is it? Heck the PSP2 is about to come out and Gran Turismo never even released once for the PSP1 (ps: it was supposed to be a launch title). What a joke...
