Since the Direct is so close, I'm only going to do one more of these:
Inkling: God, they're everywhere on these bingo cards, aren't they?
Adventure mode: I'd like that.
More Cloud: Guaranteed (How many times have I typed that now?)
Classic Classic: Wait, what?
Pichu: No. Go to your room.
Un-Smash-related: Maybe.
Krystal: I doubt it, especially if Zero reboots the series sans her.
Mii costumes: Guaranteed.
Snake: I doubt Konami would let Sakurai or Kojima do that.
Nerfs/buffs: Please nerf Shiek and Rosy. That is all.
New stages: Guaranteed.
Classic Stages: Maybe.
Stage Builder: That would be cool.
Turn off bosses: I highly doubt it.
Ballot winners: Guaranteed. This is their last chance, after all.
Wolf: Star Fox Zero. That is all.
A curveball character: Maybe. (Also, I highly doubt it would be Paper Mario)
Shantae: Well, Pirate's Curse came out in Japan, so maybe.
Sakurai memes: Guaranteed, although he didn't do it last time.
Ice Cilmbers: Geez, some people really need to let things go. THEY CAN'T WORK.
Reggie: He wasn't in the other ones, so unlikely.
Online amiibos: I doubt it.
Direct feels: Guaranteed.
Shovel Knight: I don't know-to-I doubt it. His game hasn't been released in Japan (yet).
