I completely forgot this reveal is in, what, three hours and fifteen minutes?
I'm expecting a basic reveal trailer, similar content showcase to previous trailers, where people who want to pick it apart will see hints to the types of guns, vehicles, and features the game will have. DICE is usually pretty good at condensing a lot of stuff in the trailer that have implications on the main game, even while outrageously scripted and cinematically presented.
And then a follow up at E3 with all the bits and pieces and more elaborate details.
