Can't fault the effort for a freebie. Decent length strip and some back matter. Same standard as current IDW TF so more of the same. Appreciation or lack thereof will depend on how current readers feel. Don't think it will hook any new readers.
There is a text feature at the end of the issue which recaps IDW history. Unicron has already appeared before & states when - but keep it spoiler hidden here for when. But there is no mention of D-Void so he is not Unicron or linked to him.
I'd say different planet unless we're told otherwise. We already have Beast Wars, Beast Machines, RID 2001, Prime, and probably an assortment of Armada characters that I've forgotten, running around in this and the Functionist universe. I was amazed to see BW Dinosaur Megatron and BW TM2 Megatron appeared in the same panel in an earlier issue.
