Looks like Microsoft is turning game show Hole in the Wall, the Western take on Japan's Nōkabe (aka Brain Wall or colloquially "Human Tetris"), into an Xbox 360 game. And, yes, that does seem like a very natural fit for Kinect...
Microsoft is listed as the publisher of heretofore unannounced Xbox 360 game Hole in the Wall by Germany's ratings board Unterhaltungssoftware Selbstkontrolle. GameSetWatch spotted the rating in advance of E3 2011, where the company is reported to have more than 10 Kinect games on hand to show for the first time.
Hole in the Wall started its American game show existence on the FOX network and has since been picked up by Cartoon Network.
