Yeah, very little info in the vid and PR. Two things I did take from it though. The blog says the lands at the different parks will open over several years. That pretty much means the "all opening in 2020" theory that was floating is out. Not sure what they mean by several, but at best I'd say one park per year. Since Japan is probably first, USF and even more so USH, could be a while.
The other thing is they got the right music in the vid!! Hopefully thats what's playing when you walk into the land.
