The PictoChat arena sure looks like fun. It'll probably be the least predictable stage. And demondude55 does have a point about not letting you actually alter the stage with a DS. If only they could censor out sick pictures people draw somehow.

I'll be okay whether Miis make it as playable characters or as an Assist Trophy. I'm hoping that Mach Rider will be an Assist Trophy as well.

Speaking of playable characters, I'm really hoping they update one soon.
