Mark recently released this news.
The bad news is that Kickstarter campaign for Camelot Unchained is not going to start today. The good news is that our project is currently in review. As soon as Kickstarter approves our project, we will announce the official Kickstarter launch date. We have no reason to expect that it won’t be approved next week but our project is rather “complicated” as there are a ton of moving parts, including 30 very detailed reward tiers, all the individual rewards, Founder’s Exchange (the store), etc. Due to that complexity, the holiday and the typical studio issues of weather/illness/CPU going boom/etc., it took us just a little bit longer than we thought it would to put it all together so please accept our apologies for this brief delay."
Update: Over at http://www.reddit.com/r/CamelotUnchained/ Mark made this comment.
We just got approved a few minutes ago but because we have people in Europe who follow us and because, like other Kickstarters we have some "limited" tiers, I'm not going to launch till next week because I don't want to put our European players at a disadvantage. Update to follow shortly.
