The achievements for Sonic 3 XBLA have now been revealed at Xbox360Achievements.org. Here is the link: Sonic the Hedgehog 3 Achievement List The achievement requirements seem to be very easy in my opinion. It doesnt even have an achievement for finishing the game quickly or without dieing. I think this could possibly mean they will be added with Sonic 3 & Knuckles DLC, but that is probably just me being hopeful. Still, at least this is some final proof that Sonic 3 XBLA is on the way soon.
