Sega is releasing a limited time demo for Sonic Generations over Xbox LIVE and Playstation network. There is a catch though, only classic Sonic will be available, and only 1 Act of the stage. Yes, this is rather weak for a demo, but it's at least an E3 demo everyone can try. The game isn't out for quite awhile.

It will only be available June 23rd through July 12th and afterwards will be removed from the market place. Sega has stated the demo itself will expire as well. So get on it if you want to try out the E3 build of classic Sonic!
