I thought this might be an interesting thing to bring up. The new Sonic Game, titled Sonic the Hedgehog, but rfered to as next-gen sonic, is schduled to be released as a launch title for PS3 (it's coming out at the same time for the 360). According to my info, the game pushes the limits on everything on the system. For instance in past sonic games characters were built using 1500 polygons, and if my info is correct, this game will have close to 1 million for the characters. Anyway, thought it might be of interest, but if you want to know more go to:
