Have you guys thought the retractable cord thing though the whole way?
That's going to make for some Xbox-sized controllers. Unless you're thinking it detaches at the controller and retracts into the console; in that case, it's going to make for an Xbox-sized console. It's a lose-lose situation.
Plus, what happens if the cord is attached to the console permanently and your dog chews through it? How much of a pain is it going to be to replace? Not to mention the extra cost of having 4 cords a part of the console. Those people who don't play multiplayer are going to have to pay for something they won't even use.
The only way it could be retractable is to have it as part of the controller, in which case only
this man will be able to wield one.
If you want to go with the wire/less controller, the only way it could feasibly be done correctly would be to have the cord detach from both the console and the controller.
