I think mobile phones will become the standard VR devices most people will opt to use with a headset that you insert the phone into, esp as phones become increasingly advanced, due to it being the cheapest option for most people.

I doubt it because I think a successful VR headset will have 6dof room scale tracking, hand controllers, and facial expression tracking. That will takes several well positioned cameras, plus additional cameras for eye and face tracking. I think they will be standalone devices that will potentially include AR at some point and even replace phones.
