Edit: It appears that Interplay's server went kaput presumably due to increased traffic. If you can't access the website, just wait a while and try again I suppose.
Interplay has launched a blitz of Fallout: Online media, including a new website. There is a bunch of new art and a great little flash scene on the website. You can also sign up for the Fallout: Online mailing list and register to take part in the Beta.
Whether or not this is a result of some back-room-dealings between Interplay and Bethesda over their lawsuit has yet to be determined.
Thanks very much to Frymuchan for the tip!
