Do we ever run into the Traunt siblings?

You know: “Beck-o, Randal, Dante, Michael, Eric, April, Connor, and the rest”?

I hope they are the raid bosses.

Not currently in the game, but who knows? There is a Maliwan based free content update coming late this year so I could imagine them featuring all or at least some more Traunts.
Kind of hoping for it, because they are just a funny bunch. Having another enemy Clan besides Zafords, Hodunks and Flynts (especially since the most recent Flynt is a playable character) would be nice.
