On February 28, Sony is adding a Mint Green slim PSP color to the flowery Blume series for 19.800 yen ($181). The new Mint Green color brings the total number of pastel PSP shades in Japan to four.
Beyond the new color, the second to last paragraph in the press release has a small list of upcoming PSP software. Anticipated titles like Musou Orochi, Coded Soul and Monster Hunter G are on the list. Echochrome is on there too. Perhaps, we will be wandering through monochrome mazes sooner rather than later?
