Don't think so <.<. I have the achievement though so as long as it IS coming, I'm just stacking up more things to actually use flying for. Mainly getting rare solves in Arch and alts leveling and chasing world followers and so on. ^^
Honestly, when my Bnet client made me have to download a small patch before I logged in yesterday, I thought it was going to be the flying patch for a half second there. Sadly it was not.
