Before I thought that DLC would make the game fresh and new, but now I realize that it won't. Partly this is because the DLCs probably won't modify the actual Wasteland, they'll just create a fancy new map to play around in for five hours and then say "Sorry, you can't come back". Even if there's great writing, a great story, and great gameplay, I'm just going to be spit right back out into the Mojave with a shiny new gun.
Anyways, maybe I'm extra mopey because I'm waiting for the new content to be announced, but I know there are people who feel the same way (note all the "Wat duz I doo nau?" threads)
