wait...... there's gonna be a new Wii? :/
Was announced a year ago at the last E3... Sort of out of it, aren't you, Celes? ;P
(No worries, I forgot to get hyped/caring about a lot of the newly announced things in games over the last few years. I nearly forgot it was coming myself).
Anyway, I can't watch the video (at work), but I can say with certainty it'll probably be fake. For several reasons:
1) Ocarina of Time has a strong fan-base and fans would be (for the most part) pissed off if Majora's Mask got a Wii-U re-release over the other, which only got a 3DS re-release.
2) Nintendo already announced they are working on a new Zelda game for Wii-U that will come out BEFORE any progress or release of a Majora's Mask re-release.
3) Nintendo ALSO already announced the Majora's Mask re-release WILL be on 3DS
So yeah. Sorry, it's most certainly fake.
It's awesome having these games portable and, thankfully, the 3DS is an awesome system for 3D games (unlike the original DS). I still would have loved to see a console port (had been so since the GC days), but consider the 3DS can do graphics equal to or better than the Wii right now (and probably most handheld systems to date)... To heck if I'm gonna complain. XD
