The indie hit Cave Story appears to be coming to a few other platforms. The Entertainment Software Rating Board (ESRB) has updated its rating for the game to include the PlayStation 3, Xbox 360, and Vita -- among some platforms that are more suspect.

In particular, the rating (via Eurogamer) includes a listing for the game on PlayStation 2 and PSP, but that could simply be a matter of updating it for all of Sony's platforms in one move. It's likely that this version would be based on the plus version that hit Steam last year, since it included an HD graphical overhaul.
