Sounds like it suffers from the same malaise as all the Warlord/Bolt Action stuff - ie. the issues with scale and proportion.
From my own experience, I love the metals (sculpted by Paul Hicks) and don't like the plastics (sculpted by Wojtek); the two are very different in style. The plastics have oddly gurning faces still, plus in the past although the figures themselves were that standard 'slightly chunkier than reality' wargaming style, the equipment and weapons were made true to life.
This resulted in many broken weapons when trying to release them from the sprue, and they looked like tiny children's toys in the models' hands.
I know Warlord said they were going to redesign the plastic weapons to solve the problem, but it sounds like there's still a gulf between the metal and the plastic. Not great if they're meant to sit side-by-side, even worse if these are metal components for a plastic set.
I still don't like the poses achieved with the plastics either; they all look like their clothes are a bit itchy, with their limbs poking out as far from the body as possible. This is not necessary in a plastic multi-pose set, as the Perry brothers have ably demonstrated.
Still, it sounds like there's plenty of positive in there too, so this will still sell no doubt.
