yes nintendo power had a article about it a few months ago but I was too lazy to post the entire article in this edition's...
here is the entire article from the Nintendo Power November 2008 magazine i just got today in the mai. Again, nothing new in it.
"...Among the highlights was the curiously titled Kingdom Hearts 358/2 Days, which tells the tale of protagonist Roxas's time in the villainous Organization XIII. (Series creator Tetsuya Normura insists the title be read as 'Three Five Eight Days over Two,' and promises that it will make perfect sense by the end of the game.) In that title's story mode, players will control Roxas while the computer controls a rotating cast of NPC allies. As missions are completed, they're unlocked in multiplayer mode, where up to four players can take control of various Organization XIII members and team up to fight the heartless (still no word, alas, on whether or not the game will support Nintendo Wi-Fi Connection or be restricted to local wireless play). Players report suggest that 358/2 Days has more of an action flavor than past Kingdom Hearts titles, and that you'll use the DS's Control Pad and buttons to move, jump, and attack, and the touch screen as a sort of touch-sensitive trackball that allows players to adjust the camera with their thumbs. Kingdom Hearts 358/2 Days is currently scheduled for a winter release in Japan, but the title has not been officially announced for the US."
