No need for ED glass.
My 16/3.5 AI fisheye, 105/2.5 AIS, and 200/4 AIS (all non-ED) could stand a big increase in pixels to pull more resolution out. My D700 at 12MP does not quite have enough resolution when these lenses are stopped down just a tad and will definitely help out with the wide open shots.
Sure the D800 will show their faults more, but I can always scale back to 12MP if I want to!
I think much of the old glass will hold up just fine - heck, even some of the newer AF glass will have issues with 36MP.
I should add that I will likely get a D800 sometime in the future, but I'll have to wait for the price to come down a bit, which will likely be a long time. Unless Nikon comes out with a cheaper full frame body that is D700-like, I'll make due with the D700 for a while more.
It would be nice if they came out with a D700s - maybe 24MP with higher high ISO DR and video for $2500 or so . . . . one can dream cant I?
