As far as other people know. Probably. Because they have so many people who like Fallout New Vegas, that if they make another one; everyone would want it. Hope that will get you exited! :)
Fallout New Vegas is all one game.
No, you can't get married in Fallout: New vegas, but you can have sex in the game :)
fallout new Vegas will be on PlayStation 3 and Xbox 360
A new game.
"Fallout: New Vegas" is projected to come out sometime in 2010.
Yes.
If by you mean a new Fallout game the yes, Fallout:San Francisco
New Vegas is not an expansion pack for Fallout 3 or part of the game! Fallout: New Vegas and Fallout 3 are separate games. As for "how to get there", you can purchase it almost anywhere retail video-games are sold.
I just beat the game and there is no new game plus.
Not in a normal game
I personally recommend Fallout 3 to any other Fallout game. Fallout 3 has a more organized and in my opinion interesting storyline. And you. And you can also keep the game going after you beat the main quest on Fallout 3 if you buy the DLC "Broken Steel."
