This might happen seeing the price of ETH which is more affordable than the price of bitcoin, and actually there is no need to wait for ETH 2.0 to be released, some time ago the transaction fees on ERC20 had dropped, as a result there was a surge in transactions in the ETH ecosystem, by observing this phenomenon I dare to argue that ETH will keep growing with ETH2.0 or not, he just needs to lower his transaction fees a bit.
