I played Wednesday night from 6pm till 10pm, around 75,000 playing and the game was great!!!! Hardly no lag at all, and games were easy to find. IN those 4 hours I only played with about 3 groups of people. The games just kept rolling on, everyone staying together. Most fun I have had since the first week of play. Treyarch must have been paying attention.
I may be on later 2nite.
