As spotted by the denizens of NeoGAF, the good folk of the Fallout section of Gamepedia have noticed that Bethesda Softworks have this week registered a trademark for Fallout 4, covering a range of things including merchandising and clothing but most pertinently to us - games. Of course, companies register trademarks all of the time to protect their intellectual property rights, but as Gamepedia notes, there were four months between the registering of the Fallout New Vegas trademark and Bethesda revealing the first teaser trailer.

Speculation has also been compounded when earlier this week a countdown clock appeared at - the users of Reddit later traced this website to a relatively unknown Polish developer, so we don't think it's actually related, but it's hard to deny the timing of this is certainly interesting.
