We all hope that Ethereum 2.0 will actually reduce the gas price significantly. But whether it will be something like that in the real sense is a matter of thought. Whatever I personally hope that Ethereum's gas price will be tolerable after the upgrade.
The anticipated upgrade to Ethereum 2.0 is long over due, Vitalik Buterin and his team of developers should address this scalability issues once and for all, consequently this will reduces the high cost of gas transactions, I believe the team are aware of growing demand for Basic Smart Chain from binance an alternative to ERC20 project, even TRON network is on board, if Ethereum developers don't do the needful promptly they would lose a lot interest from new developers who might divert to other lesser cost of transactions and faster network.
The situation with congested network force the transaction fees to increase a lot, with this update the chance of lowering that fees is very possible, scaling issue will be shouldered as expected by people who are still supporting ERC, like what you have said, there are many migrations that take place because of this problem.
BSC and other chain who cater those new projects are booming as developers needed to migrate to continue surviving, by using
BSC or any chain who offers lower fees investors would likely to join and participate.
Hopefully ETH 2.0 will be the solution to everyone who is still stuck with their assets that stored from ERC chain.
