From a Weibo user, new Power of the Primes art has surfaced, featuring Optimus Prime, Grimlock, Starscream, Rodimus Prime, Jazz, and Optimus Primal. It is unknown at this time what purpose these pieces are intended to serve.

Based on historical precedent, we should see wave 1 of Power of the Primes at brick and mortar at the end of 2017, so we will probably learn the purpose of this art then.
