Sega has officially announced an upcoming re-release of Sonic CD for nearly every device under the sun. Sonic CD will speed its way onto Xbox Live, PSN, PC, iOS (iPhone and iPad), Android and Windows Phone 7 "late" this year. Alas, it looks like a WiiWare release isn't in the cards, presumably because the game and its (Sega) CD-quality soundtrack would exceed Nintendo's storage limit.
Speaking of the soundtrack, Sonic CD will feature music from the Japanese and European version. Overall, the Japanese soundtrack is generally regarded as better than its American counterpart ... however, it doesn't include the classic title track "Sonic Boom," which was created for the American version. We suppose you can't have everything.
