The trailer had a lot of stuff in it from other games. Though thing's seem to be conflicting a bit. Or maybe I'm looking too hard.
0:13 The woman is a Sheikah, she has the symbol on her clothing and face.
0:21 Does anyone else think the huge emblem in background looks like that area of TP that has those ruins in the desert? Pre-ruin, obviously.
0:50 I'm not saying this is what it is but that rising wall with text on it reminded me of the Royal Tomb in OoT. There was something similar in appearance there.
0:52 That harp looks like the harp used by Sheik in OoT.
0:55 That boss looks a lot like a boss from WW.
1:02 Flooded forest (like Forest Haven in WW). I was started to think SS could be what happened between OoT and WW but other stuff makes me think otherwise.
1:11 Stuff like this. I know we don't know but, to me, that looks like a Zora but as if it's not evolved into it's humanoid shape yet. That would mean pre-OoT. Maybe it's some kind of Zora god or elder or something, who knows? Actually, it probably is some kind of god or elder. We saw a Zora in one of the first trailers.
1:18 Creation of the Master Sword.
1:30 That thing behind Zelda looks like another version of the Mirror of Twilight that Tp Spoilers:
Given how the villan I forget the name of warps around with Twili like effects (the squares and stuff), it might be connected.
1:35 Sheikah woman defending Zelda.
I think the game will be about the creation of the Master Sword, the beginning of the Sheikahs roll as Royal protectors, the coming togethor of all Hyrules races and Hyrule as it is in OoT.
I'm also thinking this bad guy that I can't remember the name of, is a Twili or whatever they were called before becoming the Twili. Ancestor of Zant, maybe.
