I was just browsing over at Sega Japan website, when I noticed a new section called Sonic Channel, which is home to a few of the new Sonic games coming soon. Now I remember reading about a new Sonic game coming out that was supposed to have Sonic CD and Sonic Fighters in it, but I didn't realise until just now that it also has Sonic R in the compilation as well. I think this new compilation is called Sonic Gems and is going to include the games mentioned above plus a load of Game Gear games.
I'm unsure of a release date but it looks like August in Japan this year, and it's coming to both Gamecube and PS2.
I've waited a long long time to play Sonic Fighters on a console, and it's finally coming, it's been nearly 10 years sonic I played it in the Arcade. The fact that Sonic CD and Sonic R are on the same disc is so awesome I can't even explain it. Sonic R has some wicked cool music in it, was one of the last Saturn games and is great fun.
