I understand the skepticism from a lot people here and all the concerns are well warranted, but I am looking at these trailers from a different angle. I don't think Nintendo is purposely hiding anything because of a lack of confidence in the product they are putting out, quite the opposite. We all know that this game is going to share a lot of what BTOW was in terms of mechanics and locations, and that is why, IMO, they are not showing anything that is actually new, in any substantive way at least.
I mean the fact that Gleeok is shown is this trailer, alone is already enough to get me excited. Yeah!! I am that much of a classic Zelda fan. hahaha
