I don't see EIP that was discussing about increasing the blocksize. Im sure that you will not be seeing lower fee in ethereum again. The only choice to increase the block size or it will still remain to be the most expensive blockchain right now. Another blockchain has been increasing its blocksize while ethereum was still getting stuck with its POS. No one know when that will happen but you can read some new EIP and if there was an EIP that said will be increasing the blocksize and it must be supported. London hardfork was making the fees even expensive than before. EIP needs to be approved by miners and this will also extend or give another delay for the implementation of EIP. Ethereum community was debating about this in the past https://cointelegraph.com/news/ethereum-community-debates-raising-the-block-size-limit-once-again
