YAY! No more random battles AND a turn-based system, anticipation just went through the roof.
Also, since it IS turn based now multi-player would be boring as HELL, glad they are focusing on the single-player now. :)
Removing online doesn't mean they're getting rid of multiplayer. Local multiplayer will still be there. I'm guessing it's because a turn based game would be problematic for this. Not for the actual battles, but for exploration: you'd be getting other friends screwing up and getting you into battles out of the blue, you'd all be sitting ducks, or you'd be sharing it between each other, and it's harder to stop one person from being a jackass and deciding to leave the area or ignore that treasure chest. THis way, you could wrest their DS or something.
I hope the online action RPG's revived as a sidegame - the rest of the company certainly isn't trying to do anything there online anyway.
