A future PS5 Pro console with a dual-CPU, dual-GPU implementation and with more RAM and storage could be in the works, if recent patent findings are to be considered.

Reports are also coming in that Sony may launch a PS5 Lite some time in H2 2021 to overcome availability issues of the current PS5 console.
