Google just revealed that Baldur's Gate 3 will be released on Stadia in 2020, so yeah they are further along then Hawke thinks they are.
I just regret that they didnt do what they promised... i mean, in June 2019 they released an update where Swen said that they will share their development process like they have done with D:OS 2 but... nothing really happened. Its been over 8 months and not even a single thing is shown, we dont even have a single screen from the gameplay. That's pity.
