A listing showed up on Amazon.de for Mirror's Edge 2, and while it doesn't have any details about the game, it is a good indication that the rumors are true -- that EA might actually be making a sequel.
I know we all want this to be true, to the point where we already have stuff in mind we want from a follow-up. I also know a lot of people like the original, and I'm no different. It was unique with its high-contrast visuals and first-person "not-a-shooter" gameplay. I would gladly play another one.
