I would like to see the new Legendaries, but I think we'll mainly get more information on the region, the new professor and some basic hint of the story. Also, this is not a Presents, so I am not expecting huge news, but it's still gonna be a lot because it's the second trailer, so most things are still unknown to us. However, I expect a Presents in June tbh. That could be when new legendaries will be revealed.
