The picture posted above was accidentally Tweeted by Anthony Burch, writer for Borderlands 2. Maybe he was entranced by his friend sleeping on that comfortable couch (though it seems like he's in a dungeon), but I'm sure he's taking some heat from Randy Pitchford right about now.
If you can't read the poster in the background, it says "Tiny Tina's Assault on Dragon Keep". Now, we'll see whether this means that Tiny Tina will be a playable character or whether she's just going to be a host for the DLC, as Mad Moxxi was for Underdome Riot for the original Borderlands.
Whatever it is, things will likely explode by way of stuffed animals.
