Emily Rogers Rumour: There's a lot of Wii U ports coming to NX

I don't think Smash is a mere port either ... I think it will be the GameCube and Wii games redone with new graphics on top of Smash U.

Just makes a lot of sense and would push lots of people to have to buy it even if the own the U/3DS game. 

I also would not be exactly stunned if the NX version of Zelda comes out *before* the Wii U version. They did it to Twilight Princess. 

Hardly, Smash Bros for NX is most likely Smash Bros 4 with all DLCs and with some new stages and characters, probably will include whole content from 3DS version too.
