OXM (The Official XBox Magazine) has a small article on the non-existence of any information regarding Fallout 3. There is a very unsettling statement which I've bolded.
Since Bethesda acquired the license to, and quietly announced development on, Fallout 3
a while back, little has been revealed about the studio's take on the
legendary post-apocalyptic franchise. What we do know is that it will
use a modified version of Oblivion's
Gamebryo engine (and thus will likely be playable in either first- or
third-person view); it'll be huge and open-ended, as that's what
Bethesda does best; and it's been in full-on development since late
2006 under the direction of Todd Howard, the executive producer who led
Oblivion to Game of the Year-contender status. We'll have more on
Fallout 3 in a forthcoming issue of OXM.
If the first concrete details about Fallout 3 appear in an Xbox magazine, and not on DAC or NMA, I predict armageddon.
