Flagging this as a rumor for now, though official confirmation will probably come very soon: according to sources reporting from Jump Festa on NeoGAF, Kingdom Hearts 358/2 Days has been pushed back from February to sometime in Spring of 2009. The delay isn't too surprising in and of itself, but the timing is, considering we only recently learned about the special edition DSi set to release with the title.
