Still missing Draenei heritage armor

Draenei and Troll HAVE to be next. I assume Pandaren will be last.

The race for the next Heritage Armor

So the only ones left are Troll, Draenei, and both Pandaren. I predict one or both of these happening. 1.) Anyone who gets the Heritage armor last is going to whine on the forums for days/weeks 2.) Pandaren are going to have the same looking armor but different colors for Huojin and Tushui.
