It seems that Obsidian made a point of addressing a lot of the issues the esteemed members of this forum had with Fallout 3: Playing up the moral ambiguity of the Brotherhood of Steel's motivations, introducing the DT system to make it more RPG-ey, the fact that creatures such as Deathclaws and Cazadores functioned as "gate" monsters, the option for pacifist playthroughs, and a much more focused narrative (to be fair, I really like the stories for the Elder Scrolls games, so I attribute the reason for Fallout 3's story not being great due to the "fish out of water" effect the setting had on Bethesda's writers).
I hope that with Bethesda looking at what Obsidian did with New Vegas that they could branch out of that BoS vs. Enclave conflict and instead look into crafting a better fiction out of other logical extrapolations of post-apocalypse societies (the Pitt being a great example, I think)
