In some cases this would require additional work from artists that would increase development time. I expect in the 2030s most people in the console/PC market would be gaming on capable devices that notably exceed the PS6 handheld, and can handle some form of mega lights implementation (
extremely demanding on current low-midrange GPUs).
Kepler_L2 claimed that the PS6 Canis APU would be closely aligned with current Panther Lake devices at 30 watts. Digital Foundry tested the configuration and found that the performance is competitive with Xbox Series S. Would you be okay with Series S class hardware holding back developers in 2032?
With improved settings to boot.

Perhaps Sony will luck out and most developers would continue to target 2060 class hardware, handhelds, and the PS5/Series S/Switch 2. Then 24GB RAM wouldn't be necessary at all for the handheld.
