They can port all of the WiiU games they like, as long as it's not at the expense of new releases for NX. That was the problem I had with the influx of PS3 remasters to PS4; GTA5, Tomb Raider and The Last of Us ended up being among the most noteworthy games on the new console in its first year.
It's all but confirmed that Zelda will debut on NX, but if ports of Splatoon or Smash end up taking precedence over new software for the console... then we have problems.
