I've said this in other threads, but a PS5 Pro whose primary selling point is better raytracing would be a horrible sales pitch. For one thing, most people don't even know what ray tracing is. For another thing, ray tracing still sucks, even on a 4090 it is extremely limited and needs to rely on all sorts of algorithmic tricks (DLSS) to give an acceptable resolution and framerate. It's not going to be that much better on a 2024 videogame console. So then you are left with some patchwork upgrades to framerate and resolution, when outside of hardcore forums like this I just don't see a lot of people complaining about the performance of PS5. We hit diminishing returns on resolution long ago, even today high-end PC users are playing games on sub-native resolution.
The primary pitch of the PS4 Pro was to take advantage of the new 4K TV you just bought. That is a simple, easy to understand sales pitch. Even then only like 20% of PS4s sold were Pros. Most people didn't care. If Sony's sales pitch with the PS5 Pro is slightly better ray tracing and, I dunno, 1800p/60fps instead of 1440p/60fps, they won't even get close to that 20%.
