I remember a post discussing whether we will have to buy new mount ranks to be able to fly in the new Azeroth (like cold weather flying), and the answer was no. However, we should be able to buy another improvement on the flight speed, to increase it to 350% or even 400% because, maybe am the only one thinking this, but Kalimdor/Eastern Kingdom seem to be WAY bigger than Outland and Northrend... Imagine flying from Eversong to Booty Bay, if the current in-game flight master has the same speed we currently have, that's ~12-15 mins in flight. But then again I might be wrong. What do you guys think?
