I hope that Microsoft/Nokia will give Wifi-Direct (or project my screen or miracast or screen mirroring or compatible Bluetooth software for NFC connection on TV) for compatible windows phones. If Microsoft don't do it then must explain us why the wp8 mobiles (eg: Lumia920) has hardware and can't be fully used. I am waiting for new good news.
Amongst other things, Miracast requires a new driver model. There's almost no return on investment for Microsoft to spend the time to write drivers for hardware they won't be utilizing much longer anyway. (As anything new will use a Snapdragon 400, 600, or 800 - not the Snapdragon S4 that older devices use).
