The 3ds version holding back the Wii U version made me angry. I don't care about the 3ds fanbase at all. If the system isn't strong enough to handle the ICE then ICE the 3ds version.
Anyway, if they do port smash to the nx, I wish they would add the starfox ship stage without having stage changes. There should be an option for any stage that moves, to choose to play any of the sections statically without any movement. It would increase the number of stages and wouldn't take anything about from people who want to play a moving stage since it would still be selectable.
