I won't be subrcribing as, like many others here, I already have most of the stuff I want from Dredd's long history. I will be picking up issue one, and possibly issue two, then I'll see if any of the others takes my fancy when I see them in the shops.
Fans like us who already have all this stuff are obviously not the main target audience for this (apart from Mr. Burdis of course) but I shared the link on Facebook when the test issue came out, and one of my comic reading friends, who has inexplicably never read any Dredd but has been looking for a way in, has immediately subscribed, and another friend has started getting it for her son.
