I really hate exclusives, of any kind. The 4H seem to relish the fact that they're making a really desirable figure like the valiant knight, the serpent men or not-Conan exclusive. Exclusives suck for all collectors, even the ones attending the cons. It seems pretty stupid, to me at least, to ask your fans to spend money on planes, hotels, food, then ask them to spend a ton of money on your toys. Seems they would sell a ton more if they just sold them online, no? I mean the phrase keep it simple exists for a reason.
The valiant knight body does have extra range on the neck, shoulders, elbows, waist, and knees. Pretty much all the new knights or knight-likes they're making since the release of the VK have the new parts. Its honestly getting to the point where I wish they made new knight parts for variety's sake. Medieval armors came in plenty of different looks and configurations, so there's plenty of reference to choose from.
That said I really liked the new knight, he looks a lot like a bunch of customs people used to do with rare parts, with that dirty, worn armor look. I wish he came with a normal human head, not just the (uhg) exclusive red eyed head.
