The Arathi are coming right?

They seem to be doing a LOT of setup for the Arathi to show up and throw everything into chaos. Seems like an interesting chance to add another player faction seeing as how the arathi empire seems legit huge. Only races mentioned tho are elves and humans. which seems like they wouldn't do that, unless they also added conquered peoples to the roster. Honestly i really like the idea of a fight with the Arathi even if we don't get a third faction. kinda has "The Seanchan showing up and messing everything up" vibes.
