Tracking might be "resolved" but man three usb3 cameras + the usb3 for the headset, is a hard sell on a lot of systems. Most people who are successfully running 3+ camera roomscale deployments have at least one if not two extra usb3 cards in their machine.
They just made a big mistake going with camera tracking, the lighthouse solution just seems much more scalable.
I actually think the opposite. Camera based tracking is the future and the Lighthouse stuff whilst good right now is going to something of a dead end. In the future we're going to be using inside-out tracked headsets which will be highly reliant on camera tech. Even more so for a workable general use AR glasses solution. So perhaps more fiddly to setup now hurting consumer adoption but better in the long term?
