Obsidian is making Fallout New Vegas because there is a group of people who hate Fallout 3, but love the other Fallout 1-2.
And they're a group of people that love Fallout 3, but hate Fallout 1-2.
So some people from Bethesda quit that company and joined Obsidian so that both groups love the same thing.
Note: The original creators of Fallout 1 and 2 broke apart. Some people stayed, and some people left. The people who stayed made the Obsidian.
They most likely will, though Obsidian is making Fallout: New Vegas (which is not Fallout 4, it's just another game in the Fallout world)
Yes, they bought the rights to the Fallout Franchise from Interplay, Obsidian entertainment is developing Fallout : New Vegas, they don't own the rights, and the game is being published by Bethesda.
Fallout New Vegas is buggy because the game engine it is run on is buggy; and also because Obsidian weren't given enough time to create Fallout New Vegas; so they had to cut a lot of content and leave many bugs unfixed.
Dead Money is the first add-on for Fallout: New Vegas, developed by Obsidian Entertainment and published by Bethesda Softworks, to be released on December 21, 2010 for the Xbox 360 platform.
Many people wonder if they hear Mark Hamill's voice at certain places in Fallout New Vegas. However it is not him, it is Obsidian's Fred Tatasciore.
Occasionally Fallout: New Vegas will freeze, but not as frequently as Fallout 3.
fallout: new vegas 2 I've heard.

Fallout New Vegas is the fifth installment in the Fallout series. It is for the Xbox 360, PS3, and the PC.

No, you can't get married in Fallout: New vegas, but you can have sex in the game :)
It has been confirmed by Obsidian that Fallout: New Vegas will not have a co-op mode.
