The PSP version of Echochrome has not been confirmed or denied for North America. Hopefully, Sony Computer Entertainment America will pick it up, but if they don’t there is another way for eager Echochrome players to experience the extra PSP puzzles in the King's English.

Sony Computer Entertainment Asia is dubbing the PSP version Echochrome Plus, which comes out in two languages traditional Chinese and English. The target release date for Echochrome Plus is sometime in March, which may or may not be simultaneous with the game’s March 19th debut in Japan.
