I mean think about it. There has been hints and teasers about Majora's Mask in ALBW as well as well as Skull Kid being in Smash bros 4 as an assist trophy. I think this is just Nintendo's way of trying to tell us that a Majora's Mask 3DS remake is in the works. Plus, Miyamoto even said that a remake for the game is highly possible.

The remake of Majora's Mask is inevitable....aside from the many hints we've seen.There has been a huge demand for a Majora's Mask remake 

 

It's only a matter of time before they announce it on a Nintendo Direct episode

what if Zelda U is a sequel to Majora Mask or part of the same timeline? ( the Child timeline.)

Also Majora's Mask soundtrack was the Club Nintendo reward, and there was a lot of other Majora references in ALBW like the mask itself, the mask cult, and the special diary seen in Hero Mode

Didn't know about the MM references in Link Between Worlds since I haven't played it yet, but if they're all there, they're likely remaking it soon. I'd really like to see that. I haven't played much of the game (I plan on playing it through during break, though), but I love what I've played. I usually hate time limits, but MM did it perfectly.
