This is an interesting turn of events considering that Interplay had developed Fallout 1 and 2 and Chris Avellone from obsidian also worked on Fallout 2. But word around the web is that Bethesda wants the whole Fallout MMO trademark back from interplay, because of lack of development and progress (via edgar-online).
Fallout: New Vegas is slated to come out 2010.
