It appears that the Russian pullout is in fact happening, though they are taking up stations in their buffer zones, and they blew up military installations on the way out.
The UN Security council is currently deadlocked, with the Russians demanding that force to reunify the provinces be specifically forbidden, and the US demanding that it not be, and that “Georgian territorial integrity” be specifically affirmed in the document.
I also heard (no link, radio report) rumors that both South Ossetia and Abkhazia will be declaring independence at some point in the near future.
