Oh yes, please produce a new DLC whilst we PS3 users still don't have Dawnguard.
I'm willing to bet that if they release DG to PS3 now then the Dawnguard forums will flood with people saying their game is f-ed up.
Zombies... I just assume it's a general comment about it being a necromancy thing. But if they do a COD zombies level.. I'm freakin' outta here.

It was something about necromancy but from one of the pics I looked at there were Draugr standing on a bridge outside of Riverwood (I'm it was a thrall or something but it didn't have the glowy bits to show that).
Let's go to.... Orisinium?

They guy who mentioned the orcs thing put up a good argument as to why it could be about them. I'll have to find the thread it was on.
