I wouldn't be surprised. They could just call it "Super Smash Bros. for NX" and be done with it. The launch version comes with all the tweaks and DLC characters from the previous generation, and just build content from that platform infinitely.
They could even add a Melee mode and a Smash 64 mode, where the physics, rules, and glitches all are tweaked to run like those older games. Throw in a throwback stage pack with HD versions of all those stages, and they've got themselves two years of expansion packs right there.
