Business did the same thing, zero'ing out about 2 weeks before the flight, then went to 9's a couple days before the departure. Plane left with biz about 1/2 full. It was very strange, so don't give up on the VIPs!
Yes, don't give up hope. I flew this route before, and upgrades always cleared the last minute for me, not matter which day.
