Yes and no; That is, not directly. If you complete the final main story mission, the game ends. However, if you do that, you can restart from the last savepoint, not complete the final mission, and continue the game as you wish.
Nothing, you can just continue playinh the game indefinetly.
None of the Fallout: New Vegas expansions allow you to continue after you beat the game.

No, the credits will role and just like fallout 3 before broken steel, your only option is to load up your last save.
No, if you want to continue your adventure, you need to buy the add-on ''broken steel''.
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."
Yes, there's a definite ending.

A pop-up will appear saying the DLC has been downloaded raising the level cap to 30. After that if you beat the game it will continue
beat the simulation
It depends. After Fallout New Vegas's recent release and the announcement of Elder Scrolls 5, a Fallout 4 could be predicted to be released in 2012, at least. If that sells well, and Bethesda decides to continue the successful series, than there likely will be a Fallout 5.
Fallout 3Once you've beat Fallout 3, you can simply go to New Game and start a new quest. With over 200 possible endings, there are many different scenarios. The only way is to wait until April and buy the Broken Steel Add-on from XBL which allows you to play more and get lvl 30.After u finish main quest just load D.L.P DISK then load game from main disk an ur pipboy will up-date at the last seen in the game b4 u get in the chamber with lyons don't finish the mission an go back to megaton and sleep then you can play all the missons you missed an the new ones.FALLOUT RULES!!::::::::::::::::::::::::::There was a way I did it, if im sure. I had all the downloadable contents from the market place:^Broken SteelMothership ZetaOperation AnchoragePoint Look OutThe PitWhen you die in the gas chamber it plays the video what happend after you die. Then you start to wake up and the downloadable content show up on your screen saying you have it while you get up. Now you can continue playing Fallout 3. I am not 100% sure but that's what happend to me.
