UPDATE:

The teaser of The Elder Scroll V: Skyrim just got on youtube with an awesome release date 11.11.11

~November 24th 2010~
“Speculation of a fifth installment has been rife ever since the release of “Oblivion”; speculation has been put to an end since November 23rd, 2010, when Eurogamer Denmark Editor-in-Chief, Kristian West, translated an article about the game to inquiring sources from the English-speaking Eurogamer magazine crew, boldly confirming the game’s existence. Most of the details are under wraps, yet West spoke a little about the game’s content and development.”
