I'm probably the last person to notice this but Lik Sang says Bleach DS is online-capable... Made by Treasure, online-capable, gives you passwords to unlock extra stuff in Bleach GC (at least the Bleach GC manual claims so)...
It also uses a touch screen support-thingies feature like JUMP Superstars.
From the trailer it looks like they put a bit more thought into it than the GC one, Bankais are more than just strong attacks on the DS and the animations look a LOT better than they do on the GC. My only complaint would be that the sprite animations could use more frames...
I wonder if this time it's a hit or a miss for Treasure? And whether this'll have multiple gameplay styles as Treasure loves to include?
