It was somewhere in his connect talks. Not sure what the timestamp was, but at several points he discussed how quest 2 was designed to meet the price target and that required making various compromises based on what components they could get cheaply and in quantity. It makes sense since the quest 2's price is impressively cheap. 

On valve's side they're much higher on the price curve, but they still have to make a different set of compromises. You could easily spend $20,000+ on optics if you wanted pristine custom state of the art stuff. Improving technology will eventually bring prices down and that will open up new options for all the headset makers.
