At the Spike VGA, Bethesda's Todd Howard took the stage to announce The Elder Scrolls V: Skyrim. While this isn't strictly related to Fallout, it also means that Fallout 4 from Bethesda Game Studios won't be out anytime soon. However, perhaps after the success of Fallout: New Vegas Obsidian will be contracted to make another Fallout, this time maybe using Skyrim's enhanced version of the engine?
Skyrim's official release date is 11/11/11 - less than a year.
While obviously we won't be covering any future news about the game, Wikia also has a newly created Skyrim Wiki, founded by one of the users of the excellent OblivioWiki. So if you want to help make a database of all things Skyrim or read the latest news about the game, go here! You can also visit Wikia's Elder Scrolls Wiki for the whole series.
