May 2011
Link doesn't work for me. :?

Anyway I think in the 20 anniversary they are gonna make the following Sonic games:
1. Sonic Generation (X360/PS3/Maybe 3DS)
2. Sonic 4: Episode 2 (Xbox Arcade/PSN/Wii ware/Iphone/Ipod)
3. A new portable sonic game or another sonic collection only this time for 3DS.
