Platinum Games has just uploaded 3D model views of some of the Metal Gear Rising Revengeance characters on their youtube channel.
So far they've uploaded some of Raiden's Revengeance body, his Metal Gear Solid 4 body which I believe is DLC, and also his normal body from the intro stage R-00. Also uploaded are the Desperado Captain and LQ-84i in both of his iterations.
I wished that these were included in the gallery mode of the game and would also show off some of the visual changes that take place to these characters in game such as Mistral's hair getting roughed up as her life drops. Still, this is pretty cool and I hope more developers start doing this in the near future.
