Yes, the Ethereum network is well on its way to upgrading its mainnet, given that the team is currently completing merger testing on public testnets.
Thus, with the merger in the Ropsten Sepolia testnet, it will be the second of three public testnets to be merged. While the Goerli/Prater testnet will be the last to test the merge before the update moves to the mainnet.
The date of this grand merger has not yet been determined, but it will happen really soon. We hope that, as Buterin said, it will be in August, but it is possible that a little later.
