Skydwarves are for sure a thing.
Most of that Tzeentch range is on a flying disc. I feel its going to be aerial warfare in Chamon with dwarf machines (i think jetpack/helicopter pack) vs the tzaangors on discs.
That pic definitely looks like a few different kits too.
Tzaangor with mixed weapons.
Tzaangor brutes with polearms.
Disc Tzaangors with polearm or bow.
Disc Tzaangor hero.
Acolytes with mixed weapons.
Add a Ogriod Doombull hero mage.
That feels pretty darn close to a Stormcast/Khorne bloodbound sized release.
Super Excited for this next wave though
