The Quest market is the VR Wii market: they are not even the same gamers. Whoever is interested in bigger games, not casual body controlled games, buy Valve, Vario, Pimax, Rift S. High end cabled VR. The only standalone (aside the new ones showed at CES) is Quest 2, but if not connected to a pc, is too weak to run anything complex.
People seem to be confused thinking that VR is equivalent to motion gaming, but motion gaming is only one of the possibilities of VR. VR itself is just immersion in virtual worlds. How you interact is just a matter of game design. And motion gaming is took as sinonimus of VR because Quest 2 is the cheapest and easiest headset to try it. Since standalone games tend to be little body controlled games, VR casual gamers, who often do not even have idea of the big games, tend to think VR IS motion controlled gaming. But it's not, it's just a trend.
To me, VR is the key to immerse in big gaming worlds like Skyrim or others, playing seated as in every other big flat game, but immersed in it, and hopefully able to manipulate the objects in the world directly with my hands. No interest in Beat Saber or similar games. And for several reasons, you can't have that kind of big games on a standalone unit at a decent quality.
That's just it. It depends by what you want to play: people interested in playing roomscale, motion controlled games, will have an unthethered, better experience on Quest 2 (and even more on Quest 3), while people interested in regular gaming but in VR with the potential interaction (like Saints and Sinners, for example), will have a far superior version on high end headsets (or a version at all).
That motion gaming market, for starters, is not what Sony is pursuing. It's a plus, a part of it, but not the focus.
