Eh. I'd be happy with the victory fanfare alone. After all, no other character got a special extended version of a victory theme, even though there are a couple of characters where they could have done it.
I dunno. There's plenty of tracks that would seem very "not Smash" or don't feature the character it's the theme of. Hanenbow or Environmental Noises, for example for the former, or the two Golden Sun tracks for the latter.
I would fully expect it to be a shortened version, though. It's a shame, but that's what happened to a couple of long, great tracks (still a bit miffed about Id~Purpose being shortened in the WiiU version, too).
I fully agree on this part though. I hope they keep the "unreal" feel of some of the tracks.
