Is it only the official playable races we'll be able to play, or do you also include some of the non-playable?

Official Playable except Worgen, who are back to Extradimensional Horrors from the beyond instead of Rogue Druids.

Also, Pandaren are Retconned to be more like the [url=http://wow.gamepedia.com/Pandaren#In_the_RPG]Non-Canon Warcraft RPG[/url]. Basically, a warrior race with a love for blades.

You can also play High Elves as well as Blood Elves, as well as [url=http://wow.gamepedia.com/Makura#RPG]Makura[/url] (Non-Canon RPG version).
