Dragon Age appeals to both lovers of classic RPGs and the younger, action-oriented audience thanks to having the option to switch between isometric and third person view. The former prefer one, the latter the other. And even if Dragon Age sold fewer copies (which wouldn't be a lot less anyway, since both sold great), it wouldn't be because it has an option to switch to isometric mode.
Also, who says it must be Bethesda who makes future Fallout titles? Who knows, if New Vegas is successful enough, Bethesda might outsource more Fallout games to Obsidian while they focus on The Elder Scrolls?
You are indeed right Myron.

Though Beth did go get those who like shooters to play the new Fallouts.
I hope that, indeed, Beth will hold more development titles to Obsidian. And, when Fallout 4 will come, it'd be great to at least hire Obsidian's writers to provide a better, deeper storyline, characters, setting and quests.

Maybe New Vegas is a "test" for Obsidian? I hope so.

I, and most other real men, prefer the FO3-way all the way.
