"Deathstroke: The Terminator by Marv Wolfman Omnibus Vol. 1" in December 2024, which is pretty much what the trade paperbacks collected a few years ago, if I'm not mistaken

Holy moly. What's going on in DC's Collected Editions department? They finally seem to be putting some serious resources into it. Just a few days ago the solicitations showed that hardcovers and softcovers of current runs will be released simultaneously, for example Ram V’s Detective Comics. And they also release the interjacent volumes too, so that the releases can sync up quickly and no softcovers are skipped. Which is a game changer for paperback readers.
And now all those omnibus editions? Awesome! (there's also Aquaman by Peter David, Secret Six by Gail Simone, Flash by William Messner-Loebs and a bunch more in the next few months)
