I reeeeeeeally can't wait for Gran Turismo 5 to come out. Forza 3 was a surprise and I don't know what I would have done if I didn't have it to feed my need for speed in the interim. However I always have been a Gran Turismo fanyboy and I probably always will be. Unless someone really screws things up.
