Although there is no official statement from either party yet, a post on the Fallout Wikia page claims that Bethesda Softworks has been denied a preliminary injunction in their current court fight against Interplay over the Fallout game license.

As we have reported previously, Bethesda Softworks and its parent company ZeniMax Media have sued Interplay, claiming that Interplay did not have the rights to re-release the previous games in the Fallout series (ZeniMax bought the Fallout IP from Interplay several years ago and of course released Fallout 3 last year). If this new report is correct, Interplay can continue to sell the older games in the series and work on "Project V13" (the name that is being used for Interplay's likely Fallout MMO project) until the lawsuit is settled in court.
