Tonight at HasCon 2017 there was a special VIP event where several new products were revealed from "Power of the Primes"! Here's what was shown:
Based on the G1 character and is also a Combiner Wars limb.
Deluxe sized team member for Abominus. Appears to have a standard "Combiner Wars" limb/port.
Don't let the Decepticon symbol over the face throw you (I believe this is because the face sculpt is still in the works). The pieces mounted on the arms are the foot pieces with ankles that can tilt.
