Based on leaked info all over the places so far. I think the touch screen is not built into the controller but it's just a standalone tablet like hardware.
I think the Wiimote Plus will continue to be used along side the tablet. Maybe plug the tablet into the remote like all the other pieces.
So, that means, you won't have to buy more than 1 tablet since the screen could be shared for multiplayers. It would be insane of Nintendo to expect consumers to buy multiple expensive controller accessories.
