I know those were not in-game assets, but the art-style and general vibe look different from Smash 4.
If they don't tweak the mechanics and use an updated version of the Smash 4 engine I could see it being a new game. Really what it needs is single-player story like Subspace emissary.
A straight port with just some new characters and skins would be really underwhelming, especially since the Wii U version already ran at 1080P and 60FPS, so there isn't any room to upgrade the performance like Mario Kart 8 had.
