Sure, you can already mouse around
on your Linux-booting or web-browsing PS3
system to your heart's content, but Epic wanted to level the FPS playing field just a bit, and is bringing keyboard and mouse support to its PS3 version of Unreal Tournament 3. Epic VP Mark Rein was concerned that having multiple control methods would give some players an unfair advantage, but apparently those problems have been worked out. In addition to bringing a potential end to those endless mouse vs. dual stick debates (unlikely), this also might mean we'll be seeing some PC-to-PS3 compatibility for online play, for the ultimate test of fanboy forum smack.
