First, one of the biggest features of controllers that I miss on PC is vibration feedback I would love to see a mouse with vibration feedback, or a gel mouse & keyboard wrist rest with vibration feedback.. I know there are some gamers out there that would not like their mouse to vibrate when getting shot while trying to make a shot but... #1 do you think its easy to make a shot while getting shot IN REAL LIFE? #2 options can always be shut off. Secondly I think there would be many users that may like a naga mouse modeled after an xbox controller. A B X Y, left/right bumpers, d-pad. The xbox one is supposed to get mouse support soon, so this would work great with xbox games on the xbox, as well as probably make "bad PC ports" just a little more tolerable on PC.
