I gotta think the biggest we will get will be shuttles (which are kind of uninteresting) and the Falcon and Slave I. Those have both been shown to be good dogfighters and are VERY iconic. I would love to see a Falcon with two turrets that can fire a turn. Redo the whole escape from the Death Star scene (one of my favorite parts!)
Yeah, the turrets would be awesome. I had wondered before if they would let the Falcon fire in 360 degrees, but I think the fact that the Ion Cannon Turret does means we can safely assume the Millennium Falcon will as well. We're definitely going to see the Millennium Falcon in this game.
As for reading too much into "large surprises," I agree that they probably weren't trying to make a pun, even if there will be larger craft in the future.
