Judging on the lightning and the smaller "street". Its obvious a town. It is quite dark, and looks a bit foggy.
I would guess
Jason Centre.
It's not foggy, but it is a dark place. Now I can be totally wrong since new engine might aswell generate day and night cycles.
But I think its a new design of Jason.
Also looking at "street", this can't be the final stage of this place. It does look nicer than it does now, but it must be more work into this, I think.
Awesome tho with a pic!
Hope we can see more sneak preveiws.. Its soon mid 08
Edit: Second though, Jason is a wiild guess
But im sticking to it.. haha
