If it's a prequel to SS we likely won't see the usual tunic as that was the uniform of the Sky Knights hence why every incarnation of Link after SS had a variant of it. It may also be possible that it is the tunic this Link is wearing but has taken more different appearance to suit this incarnation more as he may be a different kind of hero to the other incarnations with him being more hunter like with a strong focus on archery rather than sword play, he may be from the Sheikah tribe given the book/stone tablet like item he has and the artwork of the Sheikah symbol on the main site.

Well that's why I said that if it were a prequel it would be doomed to a bittersweet ending since the Hero did not yet exist.  Such a story would almost certainly have to take place during the fall of the lower realms when everything first went to crap.  Could still be cool and definitely a break from tradition for the story to end with evil defeated only temporarily and the world still wrecked and people fleeing to the sky.  It would be like having a game set during the end of the Second Age of Middle Earth during the War of the Last Alliance.  A victory, but a bittersweet one that is ultimately just a respite.  

But I am leaning towards the story being either set after all the current Zeldas or being set during the original founding of Hyrule after Skyward Sword.  

All Zelda games end in a bittersweet manner as the's no way to end the Tri-force cycle I think you also misread the events before SS, people were sent to the sky to stop them from being collateral in the battle with Demise, it's not the ending you think it is as Hylia sent everyone to the sky before her and the Hero go on to defeat Demise and lock him away. The ending would not really be any different from any other Zelda game and in a way would be similar to OOT with Ganondorf only being sealed temporarily, what gives the endings more meaning and context is not the endings itself but other games in the series, for example WW changed the perspective of the ending in OOT making it go from a great triumph to a bittersweet victory.

I'm going to go and guess that the new game is in the WW timeline as its the most technically advance timeline, in the walkthrough with Aonuma and Miyamoto when they showed the map on the gamepad the were several bodies of water which could highlight Hyrule resurfacing as new land after a long time with the land reshapen from being flooded, the enemies in the walkthrough were also similar in artisitic design to an enemy in WW. The tower of the Gods theory also points to this, the blue tunic is very similar to what WW Link wore, the bow's design is exactly like WW and TP's with its lighter colour making it closer to WW's design.

I think Aonuma talked about how he likes how AC character looks because hood, that's why they made Link here also have hood.

Epona controls will probably be good, we know that she will automatic avoid trees in order not to hit them, like Aounuma said: "real horses don't run into trees very often". :)

Well there were civilizations that clearly were around to become collateral damage in the war judging from all the ruins you find down there :P .  Unless I'm missing a key piece of information.  So my thought was you would be following the attempts of this "hero" to prevent the whole thing from going down which it obviously does not get stopped.  But I digress.

And no, you can't end the cycle but in all accept WW the actual game doesn't end with the world in very literal ruin and everyone fleeing or being sent away to be refugees.   Just saying that it would be more extreme than the norm.  

However, I will point out that the massive enemy that chased Aonuma in the original unveiling boor a very striking resemblence to the tech found in Lanaryu.  Like, extremely similar.  So I wouldn't be surprised if it was tied closer to SS for that reason.  I don't know that the WW line can happen because doesn't Ganondorf say something to the effect of his use of the Triforce to force the goddesses to act for him would end that which bound him, Zelda, and Link?  In which case, the cycle *is* broken in that timeline and Hyrule is gone for good.  Unless I missunderstood what he said.

It's more to do with the game's Ghibli inspiration even the first teaser trailer for the game was a match for the intro for Princess Mononoke where the main character is chased by Boar demon that moves in a similar manner to the monster that chases, this is Ashitaka:

AC may have inspired the type of design for the hood but blow for blow the new Link is Ashitaka in design, both characters even have a affinity for archery and even the attire is heavily similar.
