Any word on new flying mounts or anything like that?
A little, but not a lot. We're not seeing a cornucopia of mounts yet. The ones we have seen are pretty cool, though. As I mentioned yesterday in my post on the Obsidian Sanctum, they're running with the design of Zul'Aman and offering mounts as special rewards from completing 'extra challenges' in raid zones.
The Obsidian Sanctum offers up a Black Drake Mount for completing the special challenge in the 10 man version, and it seems you get a Twilight Drake from the 25 man version, but I haven't seen that personally. Either way, these drakes are pretty hard to get, at least at first. They're not quite giving them out for nothing. Other colors of drake mounts have been datamined, but we haven't seen them drop yet.
