Proof?I could post an image of the beastiary design documents if you want more proof.
Never before seen no spoilers just some concept art of some masks and a ingame screenshot. Included is a design document on making Hair using Geralt as the example(third image)
Oh and here's some triss concept art just some new clothing for her nothing else
Oh and the endings are in those design documents. So if you dont want ending spoilers set filters
BEASTIARY LEAKS(FOR PROOF)

If you care about the Witcher series, be wary of spoilers, and perhaps set up some filters in your web browser.
