Combat. I'm sure that they will fling us in the middle of some semi basic combat with the aliens. Probably showcase some weaponry slash powers but mainly I think what they'll get across is the multiplayer aspect, more so how players interact with others. What I want to see most is exploration and how you come across new players in the wild. Oh and also how you can team up with players you've never met before you make the trip to wherever you are going. Either way whatever comes out of that conference I am excited for!
