Uh, the archaeology one is harder to get than the Black Qiraji Battle Tank was in WoTLK, though.

Sadly, the new ones, the red and blue are only usable during Call of the Scarab (gj Blizzard) and the new black one appears to only be granted to already existing Scarab Lords, so I guess players that want their new Qiraji mount are shit out of luck until they find out a way to make a time machine.
Fun, Blizzard.
