My guess is the problem would be less with the uncanny valley and more "Most people don't really want to shoot other people."
So once it starts looking real, it won't be that the people creep you out. It will be, the things that you usually do to people in games will creep you out. (That and what's done to your player avatar.)
Whenver we get there, i bet Sci-Fi, non violent games and such suddenly start ruling the roost.
