Consensus layer dev call wrapped up:

1) Mainnet shadow fork #7 to take place next week.
2) Sepolia testnet beacon chain to also launch next week, TTD/merge the week after.

So Sepolia testnet could be done by Jul 1 with Goerli to follow after. Since Ropsten was done Jun 8, Sepolia planned for Jul 1, if the same one month spacing is followed Goerli could be done by start of Aug. So mainnet could be in Sep.
