It is not a multiplayer game unfortunately.
Being single-player is a very fundamental part of what makes TES games what they are. There's no possible way it could ever translate into a multiplayer game without losing something in the process. That's not to say it couldn't be successful or that it might not eventually happen - hell i'd probably even buy and play it - but it wouldn't be the same.
Besides, when you ship 7 million copies in the first week, you can afford to be a single player franchise.
