Well, folks, it's been two years -- two years and 12 days, actually. And now, because Interplay may or may not have entered into "full scale development" of the Fallout MMO it was beholden to start making by, oh, say, 12 days ago, Bethesda Softworks has, unsurprisingly, asked for its property back. Though, according to an SEC filing, no "formal action" has been taken by Fallout IP-owner Bethesda as of yet, the company has apparently made claims that Interplay is "in breach of the trademark license agreement" the two companies agreed upon back in 2007.

Rumors that Interplay has been working on a Fallout MMO arose again recently as Earthrise developer Masthead Studios offered Interplay its proprietary tools and technology for use with a project currently in-development, codenamed "Project V13." We would like to point out that while a wiki page on "Project V13" hints heavily at the codename concealing a Fallout MMO in development at Interplay, nothing official has ever been announced. And you'd think Interplay might want to do that if it wanted to keep its "trademark license agreement," no?
