Looking to expand DICE's first-person platformer Mirror's Edge beyond the Xbox 360, PC, and PS3, publisher Electronic Arts asked Backbone Entertainment (Monster Lab, Rock Band Unplugged) to create a demo for a possible Wii version of the game last Fall, according to a report from Unseen64. At least one former Backbone employee's resume confirms that the studio worked on such a project.

These two pieces of concept art uncovered by Unseen64 are purported to be for that Wii prototype, revealing what appears to be a new cel-shaded approach to the game's already distinctive graphics; of course, Backbone could have restricted this look to the concept art, not extending it to the actual demo.

The developer hasn't revealed whether it's working to bring a full Wii version to market or if EA shelved the idea, but apparently portable versions of Mirror's Edge for PSP and DS were also pitched.
