If masuda mentions the youtube page, there is definitely some kind of trailer. There might not be gameplay but I qpuldnt be shocked if there is. Im kind of wprried though that je could be trolling and the video is just lile the oras one and all it has is just the boxart and official releae date.
This is exactly why I keep telling people not to go shooting for the stars.
Sure, box art is good info, but people are hyping themselves up for tons of info, and at this point they're so high in the clouds that if all we get is an ORAS-like trailer, they won't even notice the two new legendaries in the trailer. They'll be too busy falling from the sky, complaining about the lack of information.
