I wonder how much recycled content the new models will have, at this point. For all we know they could be different...
@Tyaren was did you magic eye see so far?
I don't have magic eyes, I actually have bad eyesight, lol. I am just (maybe unhealthily?) obsessed with character models/character modelling) because it is art and basically the modern form of classic sculptures to me. Me working exclusively as a 2D artist, always striving to get anatomy, plasticity and shading as correct as possible, also reinforces the awe I have for 3D art.
I have indeed looked very closely at the models, as far as the available HD videos and 4K screens allowed. I did directly compare them with DOA5 footage and I made the assessment that the models are actually completely new, even though they look on the surface pretty much the same as DOA5 models. Team Ninja uses the exact same art style and they use the exact same character looks (facial features, hairstyles...), but the character models are still completely remodelled with a significantly higher polygon count. Texturing and shaders are also completely new.
The new costumes are obviously completely new, duh.
The character base bodies are also completely new. You easily see that on the men's bodies, which look completely different to DOA5 and finally feature the same care and detail of female bodies (excluding Zack's missing belly button, lol).
Female bodies are remodelled as well as Helena's legs and arm modelling suggest. Both male and female characters also have very detailed hands and feet now. Helena's hands are especially frail and elegant.
Let's get to the heads, faces and hair:
They do look the same at a first glance, but everything is remodelled here as well. Hair features much more polygons now to move more fluidly (though Helena's pony tail still behaves strange physics-wise), ears are rounder and Zach's bald head is now completely rounded. It had very obvious polygon edges in DOA5.
It's hard to judge in-detail facial modelling with the footage that we have so far, but the smooth and realistic face deformations of the face punch animations suggest that they significantly boosted things here as well. For deformation to look this good it needs an extremely detailed face rig and bones. The DOA5 models didn't have that detail and physics.
The only reused assets that I could make out was the hair texturing of characters, it is of higher resolution now however and should still look good.
Last but not least there are Hayabusa's, Hayate's and Kasumi's swords (minus the strings and tassles on Kasumi's sword which are new). It looks as if they use the exact same DOA5 assets. They were already back then of very high quality though, leaving Soul Calibur 6's reused weapons far behind even today.
