Any ideas what Ethereum miners will do after the Merge?

So I am wondering what the miners of Ethereum will do after the Merge. Because of the switch of POW to POS I would think that there miners cannot be used to mine ETH anymore so when I think about they will switch to mine an other cryptocurrency or switch off or sell the miners completely. As the merge is coming soon, did that already happen or can we expect some big shifts? Is this what will happen or are there other possibilities or ideas you have? So far these are the only possibilities I can see. The changes will be huge for the cryptoworld and I hope that everything works properly.
