The unique puzzle game, Echochrome, will land in Japan on March 19th. It will be available both as a PlayStation Network download for the PS3 and in UMD form.
Last month, GamerNode speculated that the PSP version would cost slightly more at retail than in digital form, but now that the price points have been divulged, "slightly" has turned into "significantly." The PSP version of the game will cost JPY 3980 ($37) - 55% more than the JPY 1800 ($17) download.
North American pricing structure has not been solidified as of yet, so there may be some changes in store for our side of the world. As for differences between the two versions of the game, none have been mentioned.
If the prices don't change, and you have both a PS3 and PSP, I'd recommend playing on the Foreman Grill.
