UPDATE: Penny Arcade 3 and Rock Band Blitz have been confirmed giving even more credibility to this list. I believe we can consider SA2 all but confirmed.
A list of upcoming XBLA titles has been leaked onto the web via NEOGAF. Allegedly, the source of this list is Microsoft’s Partnernet service, which has notoriously been the source of numerous leaks in the past, including the infamous Sonic 4 Episode 1 leak back in 2010.
Among the games listed are Sonic Adventure 2 and Vintage titles Streets of Rage and Golden Axe. Another leaked title, Rock Band Blitz, could be the title to make or break the validity of this list, as that game’s developer, Harmonix, is expected to debut their next title this weekend at PAX East. If anything becomes of these rumors, we’ll be sure to report it.
Until then, you can find the complete list of leaked titles at the source below.
Update: Rock Band Blitz has been revealed on G4.
