I'm really curious to see an engineering presentation on the Quest 2, how it utilizes the XR2 hardware, and what it adds on top. From my understanding, the XR2 is capable of doing all the tracking on its own. The previous gen of hardware was based on the 835, which did not have SLAM on-chip, and thus Oculus' tracking algorithms were the big value-add over the competition.<p>And originally, Oculus was behind the curve on hadware implementations. The Lenovo Mirage Solo was the first 6-DOF headset, a year prior to the Quest, also running the 835. The Vive Focus was in the middle of the two. So, if the XR2 is doing the heavy lifting, it would suggest a big roadblock for competitor devices has been lifted.<p>So how much of the Quest 2 is above and beyond the Qualcomm XR2 VR headset reference design minus Facebook's services integrations?
