1Up has posted their preview of Fallout 3. Highlights:

More confirmation of a viewpoint similar to the original games:

And there are similarities to Bethesda's most recent blockbuster as well -- largely because Fallout 3 uses an evolved version of the Oblivion engine. You'll recognize the first-person view, the "radiant A.I.," and the move-anything physics system...but the engine appears to have been significantly overhauled in several key areas. Take the viewpoint for example: Like in Oblivion, you can switch from first- to third-person view; but unlike Oblivion, the third-person view appears to be a viable option for actually, you know, playing the game, with an RE4-style over-the-shoulder cam that's fully customizable, even allowing you to play in an overhead perspective similar to the original games.

Minor details:

There will be no Brotherhood of Steel-style heavy-metal soundtrack. There will be no bizarrely out-of-place pop-culture reference as in Fallout 2.

Those "out of place pop culture" references were fun, I have to admit, even if they detracted from the setting. I wouldn't mind seeing some small things in Fallout 3.
