This if from the offical Oblivion FAQ site below:

http://www.elderscrolls.com/games/oblivion_faq.htm


WHAT IS THE RELEASE DATE?
Early 2006.

How long has it been in development?
Since Mid 2002.

What does the name "Oblivion" mean?
Tamriel is the world of The Elder Scrolls and Oblivion
is the equivalent of Hell in Tamriel.

Where does Oblivion take place?
In Cyrodiil, which is the capital province of Tamriel,
as well as parts of Oblivion itself.

What platforms will Oblivion be released on?
PC and Xbox 360.

What are the PC system requirements?
We don't know at this time, but it will certainly look
the best on the latest hardware available when the game is released.

Can I be a beta tester?
When we reach the stage where we need external beta testers,
we'll put out an announcement and information on how to apply.
Until then, we don't keep names or lists, so you'll have to
wait for the announcement.

Will Oblivion include multiplayer?
No, Oblivion is a single-player game only. Rather than split
our focus between two different types of gameplay, we'd rather
focus on one and make it the best single-player experience possible.

What perspective do I play the game in, first or third-person?
Both. The game is meant to be played first person. However,
you can toggle the view with the press of a button/key.
Both views are available throughout the entire game.

Will the TES Construction Set be included again?
Yes, the TES Construction Set will be included with the
PC version. It will not be available on a console.

Does the story in Oblivion pick up where Morrowind ended?
No, each chapter of the Elder Scrolls series is a different
story unto itself and isn't directly connected to any of
the other storylines. All of it adds to the lore and history
of The Elder Scrolls, but you don't have to play previous
games to know what's going on in this one.

I have lots of ideas and questions, where do I send them?
We encourage you to register on our official forums and post
your ideas and questions in the Oblivion section, where our
fans and developers share and discuss ideas and answer
questions about the game and what they'd like to see.

Are those real screenshots or are they renders?
All the screenshots are 100% authentic screenshots taken
while playing the game.

Where can I get more information on the game?
Continually visit our website and look for many previews
that are coming across all gaming publications. Information
will slowly be revealed on the game until it is released.
