I'm going to bet that Carmack will find a way to not just make the Link feel as good as native, but with a wireless dongle, and Oculus will sell the wireless dongle for $100. It will come out next year. I'm also going to bet that they will have a path left "unfixed" that modders will be able to take to run the headset at 90 Hz. I bet that Carmack will be able to come up with new algorithms to guess the position of your hands so accurately that the tracking differences will be 100% negligible between Rift S and Quest. Still, only so much can be done in software, and it will still be very heavy and high in SDE.
