The Elder Scrolls V: Skyrim Creation Kit to be Released on Tuesday

In a brief tweet, Bethesda's Pete Hines reveals the company's plans to release The Elder Scrolls V: Skyrim Creation Kit on Tuesday, February 7th. He also promises a "surprise", which, if I had to guess, just might be a small adventure to go with it:
For our Skyrim PC fans, the Creation Kit is on track for release on Tuesday. And, we also have a special surprise with it. #whatcoulditbe!?
