MH3U has higher polygon models and utilizes more complex effects than TP. Considering how low the polygon counts are and how minimal the textures (even if they are upgraded) are it shouldn't be an issue at all for the Wii U to run this game at 1080p with the fillrate and vram it has, just as it wasn't an issue for Monster Hunter 3U.  Twilight Princess isn't really all that more demanding than WW to be honest. Both games ran at a pretty much constant 30 fps on Gamecube. 

No it's not. Windwaker HD uses the same engine and code as the original, and therefore is a remaster. A remake would be OoT or MM 3D, which both use a different engine and code from their respective original.  Windwaker HD also took only 6 months to develop. 

Why is everyone focusing on the graphics. Did you expect them to make a dramatic change in art style for a realistic Zelda? They've cleaned up the quality, that's enough.

Meanwhile, there's amiibo support, including all of the Zelda characters. So something, at least, has been added to the game. And it's got to be something more than just a skin, if they're including a Midna+WolfLink amiibo in the Limited Edition - there's no actual use for Midna+WolfLink in any other game at this time, so it would be a waste to make it for just one game with just a skin.

And if they're making changes for Amiibo, they're probably making other additions, too. So let's not jump to conclusions, just yet.

But... It just looks the same?! Wow.

So? It's a remake as assets were redone and all, the engine part just tells me how efficient and reliable the original coding is, TP is a straight up HD port.

Technically the same could be said for this, the textures were redone. The meshes remain the same in both cases. The only thing WWHD has that TPHD doesn't is a revamped lighting system with added shading effects. Almost everybody calls WWHD a remaster, not a remake, and it usually is for the reason that the source code and engine are the same as the original. 

It's not worth my money, I have the Wii version and it doesn't seem like they improve it a lot. How cool it would be if they used that E3 demo? This is a HD remaster, not a remake, so definitely my money will be saved. But, how about that amiibo? It's beautiful!

Looks like I was expecting, like a remaster of a GameCube game that doesn´t have an inmortal artstyle like Wind Waker. The textures look ok for me, it's the geometry and the overall design what still feels outdated, but to change that a whole remake would be needed, wich was unrealistic at this point.

I never had the GC version of this game and I really want to play it with a "normal" controller, I guess the game will include all the gamepad features of WW, wich is cool, and even if it looks outdated it looks 5 times better than the original, so there's that, I will probably buy it since I havent play it in 8 years.

I guess the price of the game will include the amiibo, that btw looks really good. Now I want to see if they have gone the 1080p 30fps way or the 720p 60fps way. I guess is the first one, but I personally would rather have it at 60fps tbh.

Probably the game have some new stuff that they will reveal with time too. I think this is gonna be a good way to get in the mood for the new Zelda, that looks oustanding even in those 5 seconds, and also to maximize the sales by attracting more Zelda fans. Hoestly a TP remaster and Zelda U seems like a gret way to celebrate the 30th anniversary.

Zelda games tend to be 30fps these days. From the looks of it is 1080p (little aliasing and blur), but the video quality wasn't too great to tell. 

Well they only showed some graphical improvement, they did not mentioned yet any gameplay improvement, and certainly they will be some.
