Why not both?

Honestly on the side of flying ourselves, the goblins are already working on that tech (based on the ones in Brayflox hard and others) that have the wings, can't imagine why we wouldn't be able to get a "mount" that is just a set of wings that lets us glide on the ground while flying in HW content.
Confirmed 2.x mounts that will be able to fly (eventually)
Ahriman
All 6 Primal horses (not sure if Nightmare is going to or not)
Kirin
Bomb Chair
ADS
Fat Chocobo
Company Chocobo
May be another, but I think that's all confirmed at this point. Next batch to fly will be in 3.1.
