Bethesda Softworks - Interview @ Gamasutra

Bethsoft's Pete Hines has spoken to Gamasutra in what amounts to a quick company update.  They briefly touch on each of their titles (with Gamasutra erroneously referring to Fallout Online in the chapter heading instead of Fallout 3) but nothing new is revealed:

Finally, when asked about Bethesda's highly anticipated resurrection of the classic Fallout post-apocalyptic role-playing franchise, Hines was obviously coy: “We are a fairly good ways into the process. The team has ramped up, and it will be a little while longer. As is the case with all of our games, especially those of this scope, we don't really want to talk about them until they are in a state where we can show you, rather than having you simply picturing it in your minds eye.”

He added, simply: “Fallout is not a quick two year process, and we are already several years into the project.”
