I think you have every right to be confident, I know I am. All 3d Zelda games have been nothing short of masterpieces, and for the biggest part quite different from each other (I know some people take issues with SS motion controls but I like them). Couple that with what we have seen and heard so far (which isn't a whole lot I know but it gives a good impression), how ambitious Nintendo seems to be about it, and the fact they're delaying it for a full year (most likely). It really looks like they're going all out.

Of course Zelda conventions will remain, and rightly so, but I don't feel anything like ''this is so similar to WW'' or any other Zelda game. I believe they are shaking up the formula a bit

It will feel like a crossover of Zelda's combat mechanics with the kind of open world exploration had in the likes of Batman Arkham, Assassin's Creed, and Far Cry (Aonuma is a big fan of Far Cry). Not only will the world be vast, but will have a great deal of verticality.

So Arkham's grappling hook and bat-cape => Link's hookshot and sailcloth
AC's parkour and climbing => an expansion of the kind of the climbing/parkour of Skyward Sword

Dungeons and combat will still feel very Zelda like, but with greater emphasis on stealth as an option just as in Arkham or AC. But there will also be a big focus on customizing the bow and arrow.

Far Cry's variety in gunplay => An expansion of the abilities of Link's bow and arrow and other items

Build on TT's sword techniques and more forms of transportation.

No matter what people say and think, this game will never meet expectations sadly and someone will always be butthurt over the introduced mechanics/design/etc.

As for my 2 cents. I expect it to have a more open and interactive world. I think Nintendo will try and incorporate the dynamics of western RPGs into this game.

Also Aonuma stated that with Zelda U they will back to Zelda roots (Zelda NES), with big open world not knowing what exactly you need to do next.

This picture is not without reasons

Voice acting and 60fps on the NX. All I need.

Lets be realistic for moment, OoT is not only best Zelda game, but game that is considered for best game ever. OoT is first 3D Zelda game that is revolutionary (same like SM64) that brings to gaming so many completely new things that are never seen before, and not only that, game itself was almost pure perfection when was released.

So I think it would be very hard that some new Zelda game (or any other game) top Zelda OoT. Of Course, people that are played OoT recently will not have same opinion about game with people who played game in 98". Saying that, I think Zelda U can be second best Zelda game, and I at least expect  that will be one of the 3 best Zelda games ever.

You can not say "let's be realistic for a moment" and "OoT is the best Zelda game" in the same sentence. It wasn't pure perfection then, and it hasn't aged well from a gameplay perspective now.

Two 3D Zelda's have already topped OoT in design quality. Literally the only way Zelda U can be worse than that game is if it actively shoots itself in the foot like TP and SS did. It'll control better, have better presentation, have better art design with more powerful hardware to show it, have a less barren overworld, and have larger, more intricate, less segmented dungeons. It'll have better combat like every Zelda since besides SS for obvious reasons and better enemy design for combat like every Zelda since including SS. Anyone calling that game the best game of all time is far too forgiving of the game's even common flaws like a terrible camera or terrible enemy combat AI, and wouldn't have the right state of mind to be an accurate judge for whether Zelda U could surpass it in the first place.

And this wouldn't be the first time public opinion swayed to a new favorite game. Super Metroid was considered one of the best games ever until Prime became the new favorite. (Even though they're all wrong) Mario 64 is an example of a game with the same accolades as OoT that came out at the same time, and then Galaxy came and dethroned it as the universal fan favorite. Zelda U can easily be the same thing for Zelda, and it's about time. I can only talk about how overrated OoT is for so long. It'll be great to finally be able to talk about that game the way it's meant to be talked about. An excellent, important, relic of the dawn od 3D gaming, and nothing else. Just like Mario 64 and to a lesser extent, Star Fox 64.

Voice acting, orchestrated music, different story paths, side quests that actually lead to something fun, like more bosses/gear instead of just hearts, 60 fps (I doubt 60 fps will happen).

I like what I've seen so far, especially how terrain seem to be cleverly made in a way that, while still being open, it's slightly nudging you to where you can go, while not limiting your choices (similar to Pyranha Bytes games or Skellige in Withcer 3).

From what they've shown, line of sight seems to be also great, I enjoy detailed landscapes, but in open world games if there is too much vegetation and not enough vantage points, exploration can be really painful (looking at you Velen).

I'm hoping for a lot of smaller and hidden dungeons as well as some choke points with tough enemies way beyond your level, so you are forced to come back later or be very creative about it.

Also, I actually liked breakable shields in SS, so I'm hoping they keep on developing those mechanics as well.
