If you mean in regards to the story, you're not supposed to be clear on that aspect -- they're just showing us various dramatic beats out of context to give us a taste for the twists and turns. You're not supposed to understand how they all thread together.I think that is the longest trailer I've seen where I had absolutely no idea what was going on. I'm not sure if that's a good thing or not.
I think the trailer does a great job of showcasing the scale of the adventure. The most refreshing revelation is the breadth of environments, which clearly go well beyond Blossom City. Also the sheer variety of enemies and set-pieces, and of creative sequences involving the GamePad's second screen. A very dense trailer for what will hopefully be a very dense game.
