I don't believe it will happen, Eth expensive transaction fees will remain a burden for its remaining users soon it will be felt by the network because many Ethereum users/developers are already leaving the network that's why I believe that there is no change will happen on Ethereum even if the Full implementation of Eth 2.0 will be finish. if you still using Eth you must endure that monstrous fee in order to sent and ERC20 tokens to exchange and other wallets.
