Mario & Sonic At The Olympic Winter Games is coming out late 2009 for the Wii and DS.Sonic & SEGA All-Stars Racing is coming out around early 2010 for Wii, DS, Xbox 360, and PlayStation 3.
No one knows for sure. But in 2010 Sega said they are planning something BIG because it will be Sonic's 20th Anniversary game. Most fans are hoping that the game would be Sonic Adventure 3. But that's just the 20th Anniversary game. Sega also said that there will be 3 Sonic games coming out in 2011. One being the 20th Anniversary game, the other being Sonic 4 Episode II, and we believe that the 3rd will be another Mario and Sonic game, and I've heard that it will NOT be sports related.
