Dredd is Dredd you either get it or you don't so the most honest and less conflicting option is to repackage the weekly Dredd as a monthly, somewhat like the old Eagle versions, but up to date with the weekly strips. One of the great things, still, about Dredd is that he's still in his own universe and not a reboot.
Of course if they are going to do it, it will be a reboot of sorts. Ennis, I'm still unsure about. Monkey on my back is highly enjoyable but it isn't character defining like Wagner every time he writes the most basic Dredds. That's what worries me.
