Looks like Apple is currently developing its products to be connected. After some time ago Apple made products that have the same features as the iOS device, this time Apple wants to develop on his Apple TV.
Apple TV has now also come Bluetooth connections, with this then allows iOS devices to connect to your Apple TV using this connectivity. That way, the Apple TV will be fully controlled via iOS device with a Bluetooth connection.
Reportedly, they can be used later feature when Apple will update the iOS to version 6.1, which enables full unlock bluetooth. If you feel the bluetooth feature on your iOS device only limited usefulness, then the iOS 6.1 update all bluetooth function will be executed.
With the bluetooh connectivity on Apple TV, of course, will be more fun if you do Facetime with a larger screen. So, we wait for further development of this news.
