If nintendo remade skyward sword for the WiiU I would like to see voice acting so I don't get bored of reading everything. Also bumping up the graphics to HD would be a nice touch.
Nintendo remaking Skyward Sword for the Wii U would be a ridiculous thing. I'd be incredibly disappointed with their decision making if that happened. I don't really see what the game would gain besides nicer visuals and that is far from enough to justify remaking a game that is only a year old and split the fanbase. Nothing good would come of such a thing.
