They are currently working on merging the v1 and v2 chains.
tbh though very seriously likely this year, all the major infrastructure is in place
Until it’s actually released, skepticism’s the safest bet.
What do prediction markets say about whether it will be out by what times?
Sharding is definitely proving to be challenging for Ethereum, but my understanding is that it's being worked on independently of the move to PoS now.
So it's been 7 years since announcement.

Edit: Also I should highlight I'm not arguing to shift away from PoW where it makes sense.
This isn't evidence of proof of work going away. I'm not sure why you think it is. More coins will be made with PoW and the ones that have PoW today likely will stay PoW. There's no reason to believe PoW is going to shrink, just because PoS is growing.
> Would you trust PoW in the case of Ethereum Classic
No, but I trust PoW with coins that have ASIC/FGPA resistant hashing algorithms. PoS isn't without trust issues either. What do you do if/when defi starts offering greater returns than staking? Obviously there will be a large exodus in staking making it more vulnerable to majority attacks as well.
Besides, it's not clear whether PoS won't create governance problems. PoW is a pretty smart solution of proving you spent some money and pays the miners so that people who have computing power won't attack the system.
PoS is trusting rich people, hoping they won't bring down everything for who knows what profit - a government printing money to delay a market crisis, is not that far.
Also, I expect over time that fewer cryptos will use Proof of Work. Unless you're Bitcoin/Ethereum, proof of work chains get attacked all the time. Look at Ethereum Classic.
