This was partly mentioned in the Deluxe-class Repugnus thread (link) however since more details have come to light this probably deserves its own thread.
There is a listing on Amazon (link) that originally stated it was for a PotP Counterpunch but we now have more information.

It's is now listed as Transformers Power of the Primes Punch-Counterpunch and Prima Prime with the following details.
The pack is a "Special Edition" Power of the Primes Figure similar to TR Arcee and TR Grotusque.
It includes two figures, a Deluxe Class Punch/Counterpunch figure that can convert between Autobot, Decepticon, and sports car as well as a Prime Master called Prima Prime.
The package also includes 2 accessories which I assume are modern representations of his Twin Mortar Launcher and Photon Cannon.

No pictures as of yet.
