I didn't watch. What did I miss? XD
Edit:
Saw the trailer of the sea of thieves game...
You know, this seems like something that Miitomo already showed. It looks all cool and stuff because it's "new" (but not really) but after a few hours of gaming I can't really think of this being a commercial succes. Dunno how they want to sell it yet though.
You have sea fights, like in assassins creed. on a broader scale probably. But all the fun seems to be with online ppl / friends so far. So it's a community game. Because these guys have fun together. Imagine doing this alone

It will become some sort of grind-fest? Not even that? Well whatever. It seems nice but doesnt attract me (yet) I can do this in a Gmod server with TF2 graphics. Sandbox-like. But this game seems to offer less content although more polished.
Guess we'll see! Can't judge a book by its cover eh? Lol
... I seriously laughed at the getting drunk part. Although it seems 'fun' what gameplay benefit other than roleplaying could it give?
Just based on everything I see right now, this game seems to aim at several genres to attract gamers from but really fails to deliver strong arguments why I would like this game as that kind if gamer. (Trying to look from a different angles here)
This trailer did not impress me in comparison to what we saw last. It actually was a bit dissapointing. Sorry. (Imo)
