Executive producer Todd Howard states that three years is a good space between games, leading Reuters to suggest that Bethesda could deliver more post-apocalyptic role-playing goodness with Fallout 4 in three years, or 2011.

"Ten years between Fallout is a bit long, but I think there's this nostalgia factor," Howard explained. "I think it's good for people to miss things."

Former property holder Interplay is currently working on a Fallout MMO, which must have $30 million in funding and enter "full-scale" development by April 2009, with a release no later than April 2014, or Interplay loses the rights.
