It's looks like the ROG Phone 2 will have a fair bit of customized accessories for their phone. I think the controller and secondary screen attachment are cool, but doubt I'd use them much. I think the one I'd want first is the WiGig display adaptor to feed to my 55" tv. Not sure I'd use it much for gaming, but it would come in quite handy if it doubles as a basic screen mirroring or video streaming device.
