Nop. I think they did great, until that gameplay video. We didn't need it. People weren't waiting "clarification", they just wanted a big trailer as the January 2017 trailer for BOTW. And they got it in April.
When I'm talking about people I'm not talking about me, I didn't want new informations at all, Zelda games are big action / adventure games, I want to discover the games by myself and not to be spoiled. The first trailers were great because we have seen enough to be hyped, but without too big spoilers.
The gameplay video? It was the worst way to show the game and I think that many people had big concerns at this point because of this video. "it will be Minecraft 2??", "where are my dungeons??", I had to explain to my friends that it's just a gameplay video to show the new skills for Link.
It was the best quest for me because you have to explore the game and you understand why this island or this this one does exist.
