We've gotten the question a few times, "are you going to support keyboard and mouse" on the Xbox 360. The answer is no, however all hope is not lost. In my own search to be able to use a Playstation 2 style controller on my Xbox 360 (Xbox controllers suck horribly for fighting games such as Street Fighter IV and the upcoming Tekken 6) I came across this gem of a peripheral. It's made by company called XCM (http://www.xcm.cc
) and it's called the XFPS 360. This peripheral allows you to use any USB mouse and keyboard on the Xbox 360 with no compatibility issues.
The only downside to this is that it's a fairly expensive accessory, it retails for about $65 US on a few websites and it also requires you have a wired Xbox 360 controller, this is so the unit is recognized by the console and also to program the keys and buttons on your keyboard/mouse to do the actions of the controller. So if a keyboard and mouse is really what you need to play DoF on your Xbox 360, you now are able. You can see XCM's full product description here: http://www.xcm.cc/xcm_xfps_360.htm
