Bethesda might have registered and launched a new site with a countdown, and morse code message for for "11 December 2013""
The sites address is www.thesurvivor2299.com. A WHOIS check reveals that the site is registered to Zenimax Media, at their corporate address. For those playing at home, Zenimax Media is the parent company of Bethesda Game Studios.
HOWEVER the IP address traces to a hosting facility in Poland (vibiznes.pl). This would appear an unusual choice - Most of Bethesda's facilities are of course in the USA, with some zenimax sister companies present France and Ireland. The site is registered through a completely different registrar than Bethesda usually uses (GoDaddy rather than CSC domains), and does not use the normal Zenimax name server, but its own.
The font looks similar to fonts previously used in fallout games.
The Site apparently contained java script files named "Fallout.js" (Removed before we could verify - EDIT , verified, thaks WishyWitchy), but still contains "Fallout.css" as the name for the sites style sheet.
This could be it... Or it could be another game... Or it could be a troll. There's no word yet on the Bethesda press site, nor have we received any emails from them, nor any tweets...
November 15, 2013 (UTC) Given the lack of official word, and that the site seems completely divorced from Zenimax's usual IT infrastructure, we're gunna have to downgrade this to unlikely. Although there are Fallout named files, and a link to the Bethesda youtube channel in the code... Those could be done by anyone and don't prove provenance.
