I'm surprised at the lack of people speculating that it could be the original Luigi's Mansion.
For a remaster, I'd imagine it wouldn't be a Wii game, as those are still playable on the Wii U, and not an N64 games, as that would require much more work that what I feel 'remaster' implies. A gamecube game seems the most likely candidate. Mario Sunshine would be my second choice, but there are already plenty of Mario themed games, and Dark Moon on the 3ds has done well enough that Nintendo might try to get some of that success to bleed over to the Wii U.
Still doesn't stop me from wishing it would be Eternal Darkness, though.
