No comparison pics yet, but some observations. The box has six copies of the basic sprue with six bodies, and a lone little "command" sprue with two bodies, including a standard pole and, as an added gimmick, the possibility to make Richard III, much as he is depicted on the box. Thus, a whole 38 models.
The basic sprue has, as far as I can count, 12 different pairs of weapon arms. That should give significant choice in what to use as a basis for conversion, and I already spotted a couple ways how you could use two-handed weapon arms as sword and shield arms. Heads are 10 per sprue, again offering variety that isn't as necessary, but very welcome. The six bodies come legs and torso in one piece, which is slightly limting but no big deal. What I didn't know and I didn't count on is that two of the six torsos have heraldic overcoats covering torso and groin, and four of the weapon arm pairs have matching overcoat-covered shoulders. They don't look bad at all, but I was thinking of a more cold steel look, much like the 6th edition greatswords. Furthermore, I don't really like the poses of those two bodies (one is standing still, the other is leaning way too far forward), so I actually think I'll skip these torsos for now and just use the steeled ones. That still gives me 24 bodies, with twice the weapon arm pairs, for a box. The two command group bodies have overcoats too, but they look suitably dynamic and advancing, so I'd use them for standard bearer and musician (just need to find an instrument from GW plastics).
The big question then, how do they scale with GW? My initial impression is that in terms of bulk, they're quite comparable to 6th edition greatswords, which would probably be the closest comparable miniatures. The most notable discrepancy is (as was expected) the weapons, but also the hands. I was anyway thinking of using GW weapons on these, but might be I'd have to include the hand holding the weapon. Only that most GW hands holding weapons are naked, not gauntleted. How hard might it be to greenstuff naked hands into gauntlets?
