Noted in the first post is a new Transformers 4 issue comic from IDW to begin in May, called "Last Bot Standing".
Also just announced on twitter from Viz Media (who did the translations of the Japanese Manga a couple years ago), a new artbook for Transformers, "The Art and Making of Transformers War For Cybertron Trilogy"... which looks to be about the cartoon series, rather than the toyline, but it might be both.In Transformers: Last Bot Standing, the war for Cybertron is long over, yet what it started lingers at the edges of the universe and at the end of time. Readers will discover the planet Donnok, a world poised for an industrial revolution, just beginning to grasp mechanization. The planet’s future is forever changed when a shape-shifted robot from a dead civilization pays a visit.
No release date or other details, other than it coming out around our Springtime.
