I have to echo CC's message. As much as people are dying to know, the details are not going to be made public until Ted says so. As far as details are concerned, you won't be able to get those out of anyone (and least of all Navaho).
You'll just have to watch the news forum over at SK, as Ted tends to give small hints here and there about features or functionality.
I should probably stress that even when 6 goes into beta, the beta testers are very likely NOT going to be allowed to show the boards to anyone, nor talk about features and design etc. I could be wrong on that, but if I had to guess, I would say that it would be likely that those rules are enforced.
