The previously announced Hook Wasp exotic pets are going to be folded into the regular Wasp family and will no longer be exotic. Replacing them as the new exotic family in Warlords will be the Rylaks. If you’re wondering what a Rylak is, it’s the same thing as an Iron Skyreaver mount (minus the rocket boosters) as seen above.
@Bro_ketsu Update: Rylaks now tameable (exotic). Hook wasps have joined the wasp family. Still no unicorns.

I always thought the Rylaks would just get added to the Chimera family, kind of like how Hook Wasps always should have been part of the Wasp family. The major distinction is that Rylaks use ground animations instead of hovering like the old Chimeras.
Hook Wasps were set to bring some pretty awesome buffs — haste, stamina, and a slow fall — but we don’t know yet what special abilities the Rylaks will bring. Maybe they’ll just shift the old Hook Wasp ones over to them? I’d hate to lose that extra slow fall. I was getting excited by Disengage + slow fall possibilities.
Thus far the number of new pet families seems a little less than previous expansions, but this is made up somewhat by all of the new models (killer toucans? come on!). You can see some of the new pets (and all the new buffs) in this post.
