Yeah, I have seen it. But those are previs only. Kinda hard to guess what can be done with it just based on this. Here is article about RYSE pipeline => http://www.fxguide.com/featured/the-tech-of-cryteks-ryse-son-of-rome/ There was a page on Crytek about Cinebox, which I can't find right now, where they mentioned…
All of this is addressed by Cinebox. Plus Alembic. On CGTALK there is a guy that claims that his company used Cinebox to previs and FINAL quality render of more than 120 shots for "Maze Runner". Crytek used Cinebox to render commercials for TV straight from Cinebox for their game, Ryse Son of Rome.
