They already said it would be difficult to port it to the 3DS, it just doesn't have the hardware power to handle it.
The next Nintendo portable IMO will get versions of DKC: TF, Pikmin 3, Zelda U, Mario Kart 8, etc. as a way for Nintendo to make more money off those games because they're not going to sell what Nintendo wants on the Wii U alone.
And that portable IMO is coming as a new third pillar in fall 2015 anyway so I think that will work out fine.
