It is good to hear that being confirmed.

I agree that the situation is like the Uncharted trailer.

Nintendo's policy: NEVER show footage of the game if the hardware cant handle it...

I'm not sure why people doubted that in the first place, apart from very suspicious lack on any aliasing in promo shots.

don't forget that for promotional things they often times do some tricks.   i mean, i'm assuming your saying it can't be in game because of the camera angles and cuts.  for marketing purposes they can easily take real gameplay but then move the camera to different places than what the player might be able to see.  it would still technically be in-game gameplay even if you can't recreate that exact view as a player.

it's would be sort of like infamous's photo mode.

There was an earlier story on Kotaku, though it's good that we have a more reliable source.

"The breathtaking footage Nintendo showed today for its 2015 Wii U Zelda is real, a Nintendo rep tells me. I asked if it was pre-rendered. No, they said. It's in-engine. It's not a gameplay angle, for the most part, but what you saw is coming from Wii U-level hardware, it seems."

We need a proper gameplay video pretty damn soon.

Agreed. Like, 6 days ago! 

You must have missed 2011 then..

I don't remember anything. Skyward Sword?

Couple tech demos. EA showing footage not on Wii U... Ya know, like every company does
