Finally, World of Warcraft RPG: Dark Factions has a release date!  The long-awaited RPG Book will be available on June 2008. I will keep you updated should further details are given. A couple of years ago, Luke Johnson revealed during our interview the following:

Luke Johnson (Dec 2005): Dark Factions is unofficially subtitled the “Independent Player’s Guide”, because it’s like the Alliance and Horde Player’s Guides, but for independent factions and races. And Jeff Moller here worked on

One of the races we cover is the pandaren. You’ll see the pandaren written up as a new race, as well as at least one racial iconic class for them: the Wardancer. There’s also a couple prestige classes designed with pandaren in mind.
For the Pandaren one is the Brewmaster, based on the hero unit in Warcraft 3. The other one is called the Pandaren Transcendent. Here’s a quote:

“These are the pandaren’s ultimate heroes: Spiritual avatars capable of summoning vast storms of lighting, smashing mountains with their terrible fists, and breathing winds into existence.”—- Pretty rockin’, eh?
