A list with games that are coming to Xbox Live Arcade popped up on the popular gaming forum NeoGAF yesterday. While it contains games that were already announced such as Battleblock Theater and Sonic 4 Episode II, a bunch of unannounced games are included as well. Among these is Sonic Adventure 2, a game either fondly or not so fondly remembered by Sonic fans. This was posted by a forum member with only 8 posts with no information on where it came from though. Besides that, it also includes cancelled games like Bonk: Brink of Extinction and Saints Row Moneyshot, so there’s barely any credibility to this.

Or at least there wasn’t until Harmonix (the developer behind the Rock Band franchise) revealed Rock Band Blitz later on the same day, a game included on the very same list. Meaning there’s actually a possibility that the it is real and that Sonic Adventure 2 may be coming to XBLA, or was at least once in development. Other unannounced SEGA titles that may be coming to Xbox Live are more Vintage Collections with Golden Axe and Streets of Rage. The full list can be found after the jump.
