The good folks at Xboxic have done me the favor of uncovering the latest ESRB listing.  Chiefly, the emphatically named: Screwjumper!  Yes, with an exclamation point.  Details of what this game is are thin on the ground.  I figure it'll be a modern jump man with screws instead of gaps.

A suitably obtuse chain of information links this game to XBLA but (as is typical with ESRB announcements) we'll have to wait for the official announcement.
