CF 8 RC1 is open to the public. I assume that means the NDA is lifted, so I'll say you should definitely get this and play right away (if you haven't payed attention to every CF blog in the world right now :o ). This release is easily shaping up to be amazing and really shows a lot of Adobe's committment, and the benefits of them running the show.
