A brand new Bleach game is coming from Sega, Bleach: The Third Phantom.
No other details are known about it, but Sega should be revealing them soon either at Tokyo Game Show or their teaser site. You know, Treasure has a new game coming out too with a countdown clock. They made the two other Bleach DS games, but I doubt this is the same thing they are going to announce. Unless… Treasure and ESP are planning a Bleach shmup, but that's not going to happen.
Update: Levi (and now SoulCaster) pointed me to a blurry, partial scan of Bleach: The 3rd Phantom and it looks like it is a strategy RPG. The scan seemed to originate at 2chan, but the source is gone. Good thing other people are saving it for the world to see.
