The first two series of Breed were originally published by Malibu back in 1994 and 1995. But then a little thing called boom and bust happened in comics and Malibu were snapped up by Marvel. And they haven’t seemed interested in revisiting Malibu stuff in quite a while. Dynamite were rumoured as an interested publisher, but I hadn’t heard anything for a while.
Starlin has stated that he’s had the first four issues of the seven issue series completed for some time, so there shouldn’t be any schedule problems here. Expect publication next year, as well as a reissue of the original two series in collected form.
