I am going to pre-order today after seeing the video. I only care about the multiplayer and this looks like it may be the most fun online FPS of the next year-- reach included.
I've been trying to get the word out for months that Treyarch is going for the jugular with this game. They have a bigger team than the IW team that made MW2 and they have an enormous budget. I think this game will easily surpass MW2 in quality, but probably not in sales.
Most anticipated games of 2011:
Uncharted 3,Legend of Zelda: Skyward Sword, Rocksmith
Modern Warfare 3, Super Mario 3D
