Skyward Sword is way too new. There shouldn't be a remaster yet. I hope there isn't a remaster yet. But they're jumping to conclusions in the OP anyway, a costume doesn't mean anything.
Also, yes Skyward Sword's motion control is integrated in both it's puzzle and combat gameplay in such a way that they can't possibly replicate that succesfully with mere button-presses. You'd need like a dozen buttons. I'd say the best way they could replace it would maybe be using the right analogue-stick, where your movement of it would mimick the sword's movement. This would still bring problems with using the bow (because you can't move it back) and the bird (because you can't shake it) at least.
