Now, for the uninformed, Dredd isn't what one might deem a mainstream-style property. The book was always a bit subversive -- a bit on the outside of regular comic books -- taking a dark and grim look at what awaits mankind in the future. Some of the humor was a bit tongue-in-cheek, but a lot of it was just kinda/sorta bizarre though grounded in satire. There isn't a lot of detail available at this point, and I suppose that's because this thing is definitely in its early stages; but thankfully they're talking about tying it thematically back to what was accomplished in the Dredd film staring Karl Urban from 2012.
In any event, check out their YouTube.com announcement regarding the project.
