Sounds like Chime is headed for US PSN, too

Originally developed for Xbox Live Arcade as the first of OneBigGame's for-charity titles, music-based puzzler Chime is one step closer to release on PS3 via PlayStation Network. Already rated by classification boards in Australia and Germany, the game has now received an "E" rating from the ESRB.

Now this PS3 version of the game just needs to be, y'know, announced. (Hopefully with Portal's "Still Alive" included.)
