What will ETH miners do after PoS implementation?

Hello folks.

I was thinking about the shortage of GPUs and components that could prolong throughout whole 2022 (source: https://www.pcgamesn.com/intel/gaming-gpu-cpu-shortages-2023).

But when Eth2.0 is released (on June – estimated), what will happen to the GPU market?

To be more precise:

Will we face a strong sell off by the miners or will they simply move to another crypto? (not so many left tbh)

Will we see a lesser demand for new GPUs, that will result in higher availability from retailers?

I'm curious to know your opinions. If any of you is ETH miner it'd be great to hear your thinking.

Have a nice day!
