A Best Buy employee got his hands on a Fallout: New Vegas official guide early. There is some sweet info here declaring 27 main quests and 73 side quests. (100 v. about 30 in fallout 3) If you are as excited as I am, there is sooooo much here. I am 10 pages into the forum page, and no story spoilers yet. It’s completely legit as well. Enjoy.
