I'm very excited about new toy #2 today.  This is the Splitfish FragFX for the PS3.  The XBox 360 needs an accessory like this as soon as possible.  The right analog stick has been turned into a mouse, and more importantly (though I have not tested it yet) they claim to have compensated for the analog accelleration (different sensitivity based on how far you push the stick) to make it smooth as silk.  Since I've been playing with a mouse since 1995 I've had trouble playing FPS games on consoles; I actually believe that anyone who were to learn both methods for the 1st time today would find the mouse to be superior anyway.  Those who claim the dual analog controllers are "just as good" will soon be very frustrated as I circle-strafe them.
