It was really dumb of them to release a trailer when the game is still so unpolished and far way from being released. I'm betting that many of the issues pointed out already will be fixed, but most people that see this video won't understand that and will start caring less about the game. This is CS, besides Quake it's the game with the most hardcore and over protective community, and this trailer will just fuel their nerd rage.
Nevertheless I'm loving the new look of the maps, the detail is great, and I'm curious to see what the new game modes will be (looks like TDM or some sort o CTF)
