They look like normal Knight legs to me with some artistic freedom.
No-one is super excited about the legs? They look like they're triple joint like the Cerastus, which would really help Knights stop looking stumpy.
Yeah but given how reveals and new models found in art have been going, how much of this is artistic license and how much a preview of the new model.
I really meant just "some". Not a whole lot. Not enough to look like they are completely different type of legs. ^^
Also while it's true that GW killed it for Vigilus and Shadowspear with the model teasing art, it's also true that we got a bunch of new art in 8th edition without any fitting models released with it. I'll just point towards the artwork in the BA Codex with the super fancy Gravis Captain with pelt and stuff and weird winged angel-like beings in the background (with actual flapping wings, so not Sanguinary Guard).
