I think Nintendo is gonna show everything that they got for the Wii U.... why would they wait? This is literally the last Xmash Wii U is gonna see if they are really launching the NX next Xmash, so its gonna be the last big sales that they are gonna have.
Which is the point of waiting to announce the rest of Wii U stuff then? So if there is a real Pikmin 4, Twilight Princess HD, or anything else, it will be shown now.
The next Big thing is the E3 where they will show and focus in NX, so nothing for Wii U probably. The only thing, the new Zelda, which they should probably show something now, to get the people to buy the Wii U.... if they bring it to the NX as well, then they will say on the E3. If they say nothing of the new Zelda now... I would say that its been cancelled and pass it only to NX (mmm unless they dont want to eclipse Zelda TP HD... but I really doubt it... I dont remember, but didnt they announce WW HD and also spoke about the Zelda Wii U with a trailer on one same direct?
