Just noting... Amazon is only listing a digital format for the "companion" book to the Transformers '84 TPB, which has included a number of older issues that must be the material that this mini-series draws on. (I haven't read it yet, or looked at the previews in case it spoils something for me)
There might not be a physical copy of the 100 page companion book, but since it isn't expected to have any new material, comic collectors might not be upset about missing it.
