The WiiU Play-like game was announced in the ND for the summer. The name isn't confirmed, but the game's release is.
I WWHD is confirmed for fall. I think it's very likely that Mario and/or Mariokart will be released for Christmas as well, and I suspect the Retro game is close even though we haven't seen it. I think it's very realistic that all are released, though one or two may be pushed back into winter or spring. X may not come this year, but it's close. There were many different environments on display, the combat mechanics working, the vehicles good to go. I don't think it's a stretch to say it could ship within 12 months if they wanted.
SSB4 will definitely be 2014 at the earliest, same with ZeldaU. But between now and next spring I think we could be hit with a ton of 1st party quality games. I knew many were coming but confirmation is always good. And X is much further along (and better looking) than I expected, and WWHD was a nice surprise.
