I have also read this from Vitalik's personal twitter page. Now Ethereum 2.0 is going to launch which first step is Smart Contract Address released. It was under testing but from now it is under main net launch. The Genesis block will start from 1606824000 for Ethereum 2.0 which will be launched on 1st December or within 7 days after After December 1st December. Really it will open a new dimension for Ethereum network and also for Ehereum holders.
