Since there will be several Optimus Prime toys, often within the same line, I wanted to break them all down for you. Just so we get all our facts straight, I did not include anything outside Hasbro/Takara and nothing from Resue Bots, just the main lines and collector oriented toys. Also, it may be that we have more than these coming out this year.
Siege Voyager Optimus Prime: While this toy did come out in the US and Canada at the tail end of 2018, Siege is 2019's Generations line and Optimus Prime is one of the best toys from wave 1. Many countries have yet to get this line but it should be found soon.

Siege Leader Optimus Prime: Even though we are getting a voyager already, we know that a leader class Optimus will be coming too. It will be a retool of Ultra Magnus, as you can see in the art below. It will be a voyager sized Prime with a Cybertron/Galaxy Force themed cab. We do not know yet what the armoured version will look like, nor how his trailer looks like and how different it will be from Ultra Magnus.

Studio Series Voyager Movie 1 Optimus Prime: The Studio Series will also be releasing several Optimus Primes. This one is a very heavy retool of the first Studio Series Prime with different Transformations steps. This Prime can combine with upcoming Studio Series Leader Jetfire, the previous Optimus cannot.

Studio Series Voyager Bumblebee Movie Optimus Prime: Fans really liked the G1 themed design of Optimus Prime in the Bumblebee movie and Hasbro will be releasing a voyager class toy of that design.

Studio Series Leader Dark of the Moon Optimus Prime: All we know about this toy is that it will be coming out this year. We do not know if the fact that it is a leader means it will be a big toy or if that means it will be a voyager with a trailer (such as with the Siege Leader). The images below are just for reference of the character's design and what we got in the past.


Masterpiece Ver 3: This is the third Masterpiece Optimus Prime, the one with the very high MSRP that made the fandom nearly faint. It will come with a trailer and a bunch of accessories, which you can see in the image below. It will also have a Japanese voice chip and Hasbro has confirmed to us by e-mail that even though they are importing it to be sold in the US, they will not be changing anything. Meaning their release will also be speaking Japanese.

Cyberverse Ultra Optimus Prime: It can be very confusing seeing all these similar looking Cyberverse Primes. While we had a leader class toy last year, this one is a voyager sized toy. It will have a Autobot Insignia shield gimmick.

Cyberverse 1 step Optimus Prime (new mold): They will be releasing a new one step as well with an energon axe gimmick. The previous one step didn't have any gimmick aside from transforming in just one step.

G1 Reissue without trailer: 2019 is bringing us lots of G1 reissues, one being none other than G1 Optimus. This figure has already been spotted at retail.

G-Shock Optimus Prime: Part of the big Prime anniversary is a cross over with G-Shock watched where the watch base can transform into Optimus Prime. This is Japanese exclusive.
