Do we know what those spells are from?
The Icewall, Arcanosphere mage spells.
New dk and priest ability.

I'd be a little critical of that assumption. Keep in mind that dragons are a very common type of mount, so it's possible they're just doing this for that reason. If it doesn't include any new content, I'd be suspect of it. The Astral armor is more indicative of future plotlines because it has actual effort put into it in the spirit of new content, as opposed to simply being a bundle of preexisting mounts.
Hah!
We'd need at least 2 more lawsuits to get them to introduce more talents.

I will brutalize the entirety of Ardenweald if it means getting this toy.

Looks like they're gonna put in the missing Venthyr flying mount. Was weird that wasn't in with the patch itself.
Anyone else getting wow errors when opening barber shop on the ptr?
There are signs of more customization coming in the future, there's a big ID gap in between customization choices (15797 -> 18248)/options (970 -> 1516) suggesting there's either:
- A lot of scrapped customizations made post 9.0.2
- A bunch of customizations still in the pipeline for the future
- A more exciting reason I'm not going to dare write out

Very hard to tell through the way they add new options, but you could definitely fit in a bunch of races in there. It could also just be erroronously added things that got removed afterwards, but I'm going to be keeping an eye on these tables through 9.1.5's PTR phase. Could be something.
tuskarr first
Gimme Drakonids! Or Dragonmaw Orcs! Or straight up dragons!
… Honestly, anything but the Shadowlands races.
Wishing and begging for an eventual introduction of playable Shadowlands races, as I have been since we first saw them. A new expac can introduce more races, but please, the four covenant races before the end of the expansion would be amazing, I'd be so happy.
