I think everyone can agree that there has to be a second major Fall/Holiday release besides Smash Bros., right? I think it's logical that one of the "Japanesey" games comes in late summer, and smash in mid-Fall, but that still leaves a major title, probably of different core appeal than Smash. And they've already covered their Wii Series bases with Sports Club, Fit U, and Wii Party U. Following the 3D World pattern, I think it's safe to say we won't hear about it until E3. I imagine it's at least a year too soon for Zelda. At this point I'd actually put my money on a surprise console Metroid by someone other than Team Ninja or Retro.
