Resident Evil: Operation Raccoon City has been confirmed to make an appearance in GDC 2012 (March 5-9 at San Francisco, CA). The game will be part of the Programming and Visual Arts track. Ben Hanke, software engineer at Slant Six Games will host "Rigging a Resident Evil - Inside the Bone Code of Operation Raccoon City," detailing the animation techniques used in the game.

Last week's OXM Report features Mike Jones (Capcom Japan producer) talking about the differences and similarities with the main series and how the player has the possibility to completely change the outcome of the Raccoon City incident, or walk past the line and keep things intact.

Gamespot has a 20-minute preview of the game, which you can watch here.

Lastly, Operation Raccoon City has been given the Mature rating for all platforms.
