The annual Japanese guidebook of Transformers toys is becoming more reliably annular, with the next volume coming out on the same day as the 2019 edition - December 10th.
No details or images yet, or even pre-order listings, but when they do, they will be noted.


I don't know why the more recent volumes are now using the following year on the title, as they are primarily featuring the toys from the year that is just ending, like a yearbook that looks back over the past year of toys, while giving a small sneak peek at a few items from the from the next year just to tease us.
