Yup I completely agree with you. Quest 2 is an awesome game console because of the immersion. I expect AR to be as gimmick as it has been on smartphones (though I'll probably find a game or two that will be fun for few hours), but passthrough is a useful feature. My expectations on Quest 3 is exclusively better performance, to have a wider range of games.
I perfectly agree that the amount and quality games that can be squeezed on Quest 2's GPU is freaking awesome, but still PCs have better games, and I'm not just speaking of graphics. For instance "open world" games like Derail Valley doesn't seem possible when I see performance of Synthriderz on long "experiences". It looks like loading anything that isn't already in RAM is painful (which is weird for a unified memory architecture, but anyway)
