Deus Ex is definitely one ov my favorite games too, I've been playin through my latest run in between Warhammer and other shit, just got to the submarine base last, which I dread.
But anyway, I really hope DE3 will be good, so far I don't know anything at all about it, but it can't be much worse than invisible war. Hopefully, unlike most games these days, they will focus more on the gameplay and story than just the graphics.
