Apparently there's a listing for a Deluxe Repugnus in the PotP line. Looks to be an exclusive. No pics or much in the way of details yet.

If it's true, I hope there's a more widespread release of Grotusque planned as well. Though TBH I would have preferred a bit more in the way of new molds, with some remolds for the Decepticon Headmaster Juniors/1988 headmasters. Repugnus and Squeezeplay are close enough that they could have worked as retools, same for Grotusque and Fangry, and I'm pretty certain you could get a decent Horri-bull remold out of PotP Slag/Slug or Sinnertwin.
