Markets have inertia, just because a good news comes up this is not going to change the way people feel about an asset or a whole market in an immediate way.
People forgot that we are in a bear market. They did not realize that if The Merge is something too big and can have instant effect on Ethereum network, transaction fee, for users and developers, it should not be released in bear market.
If they understands it, they should not get greedy to much with The Merge. Because lot of works and upgrades must be done after The Merge. So next bull run, we will likely have them from Ethereum team, not in this bear market.
So this is a process which takes time and you will need to wait for the positive news of the ethereum network to be reflected in its price, how long should you wait? At least a few years if you ask me, as there are many indicators which point out to the markets being in a bad shape and we do not know when things will improve.
I believe that they are working to release it in next bull market, in either 2024 or 2025. I believe Ethereum can touch $20,000 in 2024 or 2025 with such upgrades.
