Kinect support

BEFORE YOU CASTRATE ME PLEASE HEAR ME OUT)
Not ingame shoehorning of the action or controls. Just one feature with Kinect support, the ability to help me construct my face. Don't act like you never did it, "I'll just move the nose up one more....no wait that doesn't look right...back down to slider counts. How long has it taken me to get this right, ah who cares I'm finally done!" Then you hit the back button to come out of the slider menu for your virtual make over and you accidentally go too far and reset the whole thing. Just, Look Down, Look Up, Look Left, Look Right and have it attempt to do its best to copy my face. That would be great.
Stat-Transfer Playable Characters for multiplayer: Essentially allowing co-op Shepard fun without worrying about why there are 2 Shepards. Allow us to take control of Stat-copies for taliored MP Co-Op or, if you are so inclined, PvP matches. Now personally I dont think games need to cater for MP, Mass Effect proved that with a strong SP you don't need to compensate for anything even in a shooter (/ rpg), but with the fight retuning to Earth this could be a good chance to put in some Co-Op "Earth Forces" MP, defending landmark buildings or retaking areas or infiltrating to recover data / people/ whatever.
Drone Control: Leaves you open to attack but you can assume direct control of your drones.
