might never be possible in WoD

Thanks for the answer.

I have to admit, though, I'm a bit taken aback at the possibility that flight might never be possible in WoD. The zone design work so far has to have taken the possibility of flight into account, right? (Isn't that one of the reasons all those sell Wow Gold vanilla zones had to be redesigned for Cataclysm?) I'd assumed it was just PvP zones and TI-like content that would be flight restricted on a long-term basis.

Permanently removing flight for an entire expansion is quite a bit more drastic than anything I thought you were talking about.
