Seems like Sony's Rolly really is due out soon, and it'll be available in a black body version with a matching black cradle, as hinted at by the FCC filing. If black's too boring for you, then you'll also be able to trick your Rolly out with blue, red or silver replacement "arms". Maybe they're "wings"? Whichever: the little rolling, MP3-playing guy will be out in black from April 19th in Japan for around $400, while a colored arm set will cost around $15. Presumably Rolly will be rolling up on US shores sometimes soon after. [AV Watch]
