Will there be any DLC announcements this weekend @ PAX?

We all know that some sort of DLC is on it's way. Whether it be Crossfire maps, more Blitz maps/challenges (which I'm hoping for!), maybe new weapons/skills? Whatever it is, I'm sure it's something the fans want. For those who don't know, PAX is this weekend and it's being sponsored by all the great development companies, including Uber Entertainment.

Which brings me to my main concern. What will be demoed at the Uber booth?

If they told us now, they wouldn't really be announcing it at PAX.

But yeah, more maps, please! I love all the current maps (except Steel Peel, and I don't hate that one; I just prefer the others), but more variety would be nice.
