Expert Riding (Skill 225)
150% flying mount speed; 60% land mount speed
Requires level 60
Cost: 600 gold (faction discounts now apply)
Mount Cost: 50 gold
Can now be learned in Honor Hold (Alliance) or Thrallmar (Horde)
Flight Form is something we learn at level 68 and it only grants 60% speed increase, the logical thing for Blizzard would be to lower it's level to 60 and also increase the speed by 150%.
I have seen nothing to suggest that they are doing that but i'm pretty sure they will once they realize this -.-
