Be impressed if IDW is in business long enough to finish... I should probably track down th3 GIJoe classics volumes I’ve missed before they go under...
Excellent, missed this news among the Unicron kerfuffle. I do hope they pick up the release pace though, it'll be 2021 before we get to Revolution...
