FYI; this post was more in regards to any "new" info about which consoles will be supported. The following link has the most "up-to-date" info about this subject I know:

Keep in mind that much of the interviewing which was done about Fallout 3 was done when the title was discussed at E3 2005, which was almost a year ago. Which is to say, this info may be a bit outdated (although Bethesda may not have released anything on this yet, given how tight-lipped they are about everything).
Edited:
I suppose once they make their "official" announcement about the game they'll release this info.
