The action-puzzler Exit is making the jump from the PlayStation Portable to Xbox Live Arcade, following in the footsteps of Lumines and Puzzle Quest. 

Ubisoft and Taito's 2D game will be available only in Japan this summer for 800 Microsoft points.  There is no word yet on a possible North American/European release.

Exit, released last year for PSP, casts players as Mr. ESC, an "escapologist".  Players have to guide hapless disaster victims out of dangerous situations in a sort of platformer, art deco version of Lemmings.  

The XBLA version of Exit will have additional content, but there is no word yet on what this content exactly is.  Hopefully it won't be the horrendous price-gouging that Lumines Live is infamous for.
