I'm glad I can enjoy all the Fallout

.
That being said I definitely agree Obsidian did it better and Fallout 2 was excellent from a roleplaying game/writing aspect. 2 is better than the new school but I like the real time action introduced by Bethesda. So New Vegas is my favorite fallout cause it's a good compromise between the better writing and roleplaying ability of the old school Fallouts but the gameplay I like better (though I also enjoy turn based). It's my perfect game - so far though I admit even with Bethesda's weaknesses from what I see 4 might actually surpass it. And yes, I do see where there might be problems in 4, my biggest concern being dialogue choice. Appreciate each game for what it is, ya know? Bethesda games have a lot of flaws. But they have a lot of stuff they do so well that they are really fun regardless of those flaws.
At this point, my ideal would be let Bethesda make the big games that introduce big new ideas (like the crafting buildings in the Fallout world). And then let Obsidian have their hand at fixing the stuff that Bethesda doesn't do write. You get really fun games, and Obsidian will make what was really good into the perfect game (imho). Also, Obsidian would put Fallout on the West Coast (I prefer the west myself) so that's also another reason I want them to do another (But it's a small reason).
