For those of you who do not know, 358/2 Days and Birth by Sleep were not the only Kingdom Hearts games announced. There was one other game announced. Kingdom Hearts:coded is ANOTHER installment in the Kingdom Hearts series. This game takes place AFTER Kingdom Hearts II and stars a virtual Sora. The game is currently being released in Japan through monthly episodes...ON CELL PHONES!! WHY CELL PHONES FOR A KINGDOM HEARTS GAME!?
But, the game looks like a PSP game! I do not know about this game being released outside of Japan for sure, but I heard Japan wants to release this game and Birth by Sleep outside of Japan.

If this game does get released outside of Japan, there is NO WAY this game can be released on western cell phones. What do you think it can be released on? I say it can be released on the PSP [and I even heard a rumor about it], or in downloadable episode format on the PlayStation Network.

Im interested in 358/2 days. But a cell phone game. now thats a bad idea. It may work with final fantasy, but KH!

i dare to say dsiware, like cristal defenders, but who knows?

LOL, there is no WAY that is going to happen. Maybe it can be released on the PSP's online store.
Final Fantasy Agito XIII was going to be relased in cell phones, but Square-Enix was smart enough to release it on the PSP instead.
