As reported by Cointelegraph, the next key milestone on Ethereum’s roadmap is the Shanghai upgrade, which will enable withdrawals for ETH stakers/validators from the Beacon Chain — among other things.
Additionally, a set of previously agreed upon EIPs will roll out alongside Shanghai, the list includes EIP-3651: Warm Coinbase, EIP-3855: PUSH0 instruction, EIP-3860: Limit and meter init code and EIP-4895: Beacon chain push withdrawals as operations.
After all of this is completed, the network’s next major event and final part of the roadmap is the Sharding upgrade, which is expected to roll out over 2023 and 2024.
