The latest issue of Japanese gaming magazine Famitsu holds two pages dedicated to Metal Gear Rising Revengeance (click the images to enlarge).
The first page seems to be about the Crying Wolf-like enemy from the game called LQ-84i. At the bottom of the second page, you can see some licensed clothing for the game. It looks like there will be three different sets consisting of a pair of pants and a sweater. They will release on December 10th for a price of 1500 yen.
