The cat-- I mean, the Dino's are out of the bag. Fresh from the first HasCon 2017 are the official images of Transformers Power of the Primes Optimus Prime and Dinobots.

As revealed that the Dinobots are now finally together in the series: Grimlock, Slag (now known as Slug), Sludge, Snarl and Swoop in their classic Generation 1 look. Also, they'll be joining a new member in this line; the first female Dinobot, Slash will debut as a Legends class toy. As also revealed, the Dinobots is now a combiner team with Grimmy as the center (since he's a Voyager class figure and the rest are Deluxe scale), they form Volcanicus as shown with an art and prototype toy below (images from the HasCon panel talk slideshow, courtesy of TFW2005).

Aside from the Dinobots, Hasbro will also be releasing a new Optimus Prime figure which is a Leader class size, with more TF Masterpiece aesthetic design in the toy. Just like the PotP Rodimus Prime, Optimus is an evolving Transformer which the cab transforms to Orion Pax (his past form) and combining with the trailer he evolves to Optimus Prime. Also will be releasing is the Micronus with Cloudburst armor which the figure transforms into a engine (a Titan Master retool) which can also be inserted onto to the Power of the Primes figures. His Decoy armor Cloudburst; which is homage to the G1 Pretender toy, is Micronus armor form by inserting him in the shell. Aslo, Cloudburst transforms into a weapon which you can attach Micronus outside of the shell.

Optimus, Grimlock, Swoop, Slash, and Micronus will be released as the 1st wave of assortment along with the other previously revealed Power of the Primes such as Rodimus Prime. The rest of the remaining Dinobots will be released in the 2nd wave. On the footnote, Hasbro also teased us that Predaking will be the next released combiner in the line soon (image below). No word as of yet when these figures will be released.
