So you've probably already seen by now, but six new mounts have appeared in the new 6.2.2 database (and I'm guessing the landing of 6.2.2 on the PTR means that 6.2.1 and flying must be going live very soon!).
Not all six are likely to appear with 6.2.2, unless that patch is delayed until the end of the year! One is a Winter Veil mount, another is the Collector's Edition mount, so we're unlikely to see either for a while.
The six are up on Warcraft Mounts. Unfortunately the moose and felstalker don't have models in the database yet, so we can't get good images. We're having to rely on the ones released by Blizzard.
In summary:
Heavenly Azure Cloud Serpent (with which I am in love!) It's the upcoming 300 mounts (on one character) achievement reward.
Eclipse Dragonhawk may be purchased from a new Timewalking Vendor in Shattrath, using Timewarped Badges earned from Timewalking Dungeons. Time.
Ironbound Wraithcharger may be purchased from a new Timewalking Vendor in Dalaran, also using Timewarped Badges.
Minion of Grumpus is related to Winter Veil. I'm not sure how, yet. Maybe it'll be a new boss drop, but if so that's not mentioned. The flavour text also suggests it may be an event on Draenor, though I'm not aware of yetis being a Draenor thing. I can't help wishing they'd turned the Greench into a mount instead, but unfortunately that's the older model and isn't suitable.
Grove Warden, our long-awaited moose mount! It's quite pretty. It's a new Store mount.
Illidari Felstalker, the new Collector's Edition mount for Legion. It looks pretty cool though for the CE I would have anticipated something that was versatile and could also fly. Maybe it'll sprout demonic wings?
