PS5, kinda famously, has no exclusive games. I doubt it would be that taxing on devs to essentially create a build that changes it from Ultra settings to High equivalent to the PC versions when they're all running on an x86 platform. The Series S is just garbage hardware that Microsoft should have never released, the Z1E already outperforms it handily.

I also, out of curiosity, did a search for the "Z2E" and it looks like a large leak surrounding it hit last month: https://www.gamesradar.com/hardware/handhelds/the-amd-chip-that-could-power-next-gen-handhelds-just-leaked-but-rumored-specs-keep-shifting/

This chip would be more than capable of matching the PS5's APU. But the Z2 they're releasing alongside it will be decently cheaper while matching the Z1E's performance. So it'll come down to whether Sony prioritises cost or performance. My money's on cost though, they're going to want this thing to be cheaper than a Steam Deck, and the Z2E will put it in Legion Go/Ally X price territory.
