there are rumors that BG3 will be released in 2020, but as the others mentioned before, Larian Studios said in 2019 that they will bring it out when it's ready. This could also mean that the release will be in 2021.
Guess the only thing you can do at the moment is keeping an eye out in the internet and in social media channels (e.g. Larian Studios) to receive new information when new info-bits about BG3 are available.
I can't wait too for the game, super excited!
Hope it’s soon. Bought stadia only for Baldurs Gate. But with the situation now would rather the people involved in the development of this game and all their loved ones are safe and well!
