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.

Giggity giggity.
On the serious side, even Garage Games only mentions Screwjump as a title and nothing more. No real information on it at all other than being from a WI developer.
