wowhead put out a giant 6.0.2 prepatch guide
covering 6.0 changes in much more detail, including what new things there are to do while waiting for the Warlords launch. I will link to it at the end of my post.
In the absence of traditional 6.0 class guides, people might want to look at the class guides
focusing on changes. They aren't based on theorycrafting, so they won't tell you how to gear or optimize your rotation, but they have a really thorough look at the changes you will see, as well as what Blizzard developers have said on twitter or the forums about the class.
