It already is a platform in and of itself. Oculus Quest was the first of many still to come VR consoles.Unless it becomes a platform in and of itself and not an accessory or add-on it will never become mainstream and it will be nothing but an enthusiast toy.
With that being said I absolutely think with advances in technology it can become a platform in and of itself. Either that or it will have to be packed in with every console.
As for consoles, Sony even put forth the possibility that at some point in the future, consoles may just be peripherals for VR HMDs.
