There's already a keyboard and mouse for the Playstation 2, and since the Xbox is basically a small computer I'm sure they're going to have those for the Xbox, too. They even had a mouse and keyboard for the Dreamcast.

BTW, I played that Freedom Force demo. It's ok so far. It has really lame dialogue just like a really stupid super hero cartoon. You can even pick up cars and throw them at the bad guys. I've gotten to the second level where I have to command 4 heros at once. I didn't do a very good job. I got my butt kicked. I guess it's going to take a little time to get used to since I don't play these types of games very often.
