There you go they've finally given a specific day for it, the team announced on their Facebook page that the Creation Kit is going to be released on the coming Tuesday (7th Feb).
There's also mention of a special surprise to go with the kit's release, which rumours are hinting is an official High-Res texture pack.
Valve kind of ruined the surprise with their lack of skill in hiding things: http://i.imgur.com/9RKcH.png
