Widescreen, possibly if you inject the N64 version you can set it to inject with widescreen settings - can't say if forcing widescreen will look the best or not though. 60 FPS, not yet. In the future, Ship Of Harkinian that ported Ocarina of Time may do Majora, if the decompilation has been completed to a satisfactory level, but it would first be a PC port most likely before gaining Wii U support, so it is probably still a bit off in the future. When that arrives it will likely have the option to go up to 60 FPS.
