Teaser Trailer.
"From the makers of Fallout: New Vegas", they're going off the hype of NV before it's even out.
Also notice how it's on Xbox 360, PS3 and PC. I doubt they're going to try and make it isometric like DS1 or 2 (not that I've played either, I just know they are isometric, I actually saw DS1 in a charity shop the other day but it was £10 for god knows why, who prices that shit?).
