EIP-5133 updated to change block adjustment to 700,000 blocks. Devs are now targeting mid-Sep for the merge as stated in the edited EIP.
When we will reach near that block I am pretty confident that the devs will target the merge for some more months later.It will be edited again and as a bare minimum I predict that block to be real maybe June 2023 as the earliest or early 2024 as the latest if it will ever be implemented.
A lot is being done for real in the Ethereum Network but I think we will still have Ethereum mining for a minimum of one year,one a pessimistic note though we may have it until the end of this year.
