All they've posted is what seems to be this image, not much to go on right? Don't see much hype and people are freaking out about one picture. Bethesda mentioned they'll be discussing, and revealing more about this at E3.
The estimated release for the DLC is this summer.

What's everyone's opinion? Mine is, I'm not excited. I'll need to see more.
