SOE has announced that, later this month, they will be release two new types of mounts: Leapers and Gliders.

They will do exactly what their names would suggest, they jump and/or glide.  As with the flying mounts; they will be available through quests and there will be both a tradeskill and non-tradeskill version of the mounts.

Leapers will be available starting at level 30 and gliders will be available starting at level 60.  Flying mounts are still restricted to level 85+.

You can read the full details and see some pictures of the new mounts on the official announcement page.
