I wasn't sold on Dredd's head from the promo images, as others have said, but have to say it looks great in person and has won me over. The Dredd that comes with the Lawmaster set looks like it has a new headsculpt though, so perhaps it'll be more of a variant figure.
I admit, I was hesitant at first but I've gone all-in on these. The first few looked nice but as others have said, were characters we've all seen as figures before. It was when they announced Fire, Anderson and the Klegg they caught my attention properly. There's some nice variety there.
I do think the range needs more focus on unique sculpts as opposed to repaints. I can understand why it's being done but admittedly I'm rolling my eyes a little with every announcement of another B&W variant - nice as a novelty to begin with, but I think if they want lower-production-cost variants they could achieve far more by being a little more creative with paint and accessories. For example, use the CJ shield from Cal and make a Chief Judge Hershey variant. Or do a small sculpt edit with blue colour scheme and make a Hell Street Blues vampire Hershey. Give Dredd his Apocalypse War bullet-hole badge with some battle damage, or paint him up as a corrupted Kraken. I'd much more happily spend money on that than a simple B&W version of the exact same figure.
Moving forward, what characters would everyone like to see? I think anything from the following would add some nice variation to the line;
Armitage
Chopper with powerboard
DeMarco (P.I. as opposed to Judge uniform for variety)
Devlin Waugh
Don Uggie
Dredd 2012 - Dredd and Anderson
Fink Angel with Ratty
Mechanismo Mk.1 (larger scale like the Klegg)
Metta Lawson
Preacher Cain
Shimura (with cloak)
Tweak
Walter the Wobot
PS: Those who ordered from Zavvi; what is their packing like on arrival? I hope they box them properly and don't just ship the figure pack in a plastic wrap!
