The above line is happening in PTR, and may (I'm not holding my breath until we get an actual "Confirmed!"..) happen in live in 4.2..All Hunter Pets - Do NOT despawn anymore when you mount, Flying will despawn your pet though.
But would anyone else like to see it that if we have a flying pet, such as my lovely Aquila (the decrypt eagle I have), when we mount up on a flying mount.. the flying mounts don't go away.. but instead fly by our side?
I know we've had to ask for five years for our ground mounts to return to our side.. (trust me.. I've been playing for six years.. and been waiting for this moment to return..) but does anyone else think that eventually Blizzard could do this for us.. because there isn't much that our aerial pets could aggro while we're flying..
Keeping my paws crossed here..
