To be honest, I am still not expecting Ethereum 2.0 on the date said, there are already a lot of times, multiple times that this feature on Ethereum was delayed, years ago. I understand how it is difficult for Ethereum especially since there are billions of funds running on the Ethereum network, they must be careful.
Speaking of the price, I believe yes, there's a huge spike for sure for this update, either pump or dump, because we still don't know how the update will go.
