the multiplayer is so awesome... I'm trying to drag myself away from the multiplayer in order to finish the campaign

..... difficult for me to quantify how many hours of gameplay you will get from the multiplayer experience but it's far more game time than you will get from most games out there. In my case I've already played more starcraft 2 than any other game this year; well maybe I amassed more hours playing mass effect 2 but will soon catch up
This game totally owns, worth every cent... I had such high expectations and for me to say all those expectations were met + more is a very bold but true statement.
If you dont have it, go get it... if you pirated it and cant access battle.net, don't expect to get something you never paid for in the first place. (this last statement not intended specifically for the poster)
