Following the discovery of what many believe to be a Fallout 4 teaser site , Fallout publisher Bethesda Softworks has trademarked the game in Europe.

The Fallout 4 website of the Office for Harmonization in the Internal Markets , which is the official trademark office of the European Union.While trademarks should never be taken as 100% confirmation of a game's existence, the timing seems more than coincidental considering the discovery of 'The Survivor 2299' teaser site recently, registered to Bethesda's parent company ZeniMax Media Inc. Further, Bethesda has had the opportunity to trademark the game for years; why now?Bethesda declined to comment on whether or not it owned the Survivor 2299 web domain, which is counting down to December 11 in Morse code. (Thanks, Redditors!)We'll find out in December whether these clues are actually proof of something, or whether we're getting radiation-hot under the collar for nothing.
