It's been a few months away since at least 2018 - https://medium.com/@jyspark/getting-prepared-for-ethereum-po...

And I can find talk about it being 'soon' from 2016 - https://stackoverflow.com/questions/33802343/when-will-ether...

So I think it's perfectly good faith to say we've been hearing about the 'imminent' switch to PoS for several years now.
