worgen and troll flight forms

They're all made and ready to go, why aren't they in the game yet? Did Blizzard in its unfathomable wisdom decide against them? Why?

Just, why?
I hope you're implication is correct and they just haven't gotten them all perfect yet. Blame my apprehension on the placeholder travel form that never got replaced...
Perhaps they have noticed the problem the troll forms and decided to fix all of it in one patch instead of once again expanding the wait time. For example, what if they decided to re customize the moonkin forms while they are modifying druids? Night elves get the antler moonkin form, Trolls get the same colored moonkin form they have now except now has tusk and possibly another trait of the trolls such as a mohawk to match the bear and cat form, and worgen moonkin forms might have mane around the facial area like their cat and bear form. I think that would be interesting

you should check the PTR before asking, they may be included
nope not on the PTR.

I just wish we could get word on whether it's that they're not implemented fully yet, or if it's final.

Cuz you just know that someone out there made a troll druid and when he sees his brown bird turn into a green bat he'll come here complaining about it because he just doesn't understand how awesome a green bat is.
They never said that they were sc!##@d, but i think their all finished, (you can see models/movement on wowhead), now this doesn't confirm 100% that they are complete, but i think they might be holding them for a later patch so that they can give all un-updated forms updates for the Worgen and Troll all at once.
