Not gonna happen guys. Microsoft would laugh at me if I called and said we have 91 people that want to buy a controller. Try closer to 10,000.
That being said, I'm going to close this poll.
I've only seen wireless receivers and wireless controllers sold separately, with the receivers running for a good extra 20 bucks.
Perhaps this is different packaging/branding/products, but I'd definitely double check that if this poll goes anywhere.
