Liam Robertson is a respected journalist known for having insider information and following it up. One of his sources tipped him off concerning the Stadia Connect event and mentioned that Baldur’s Gate 3 is planned to open the show.
Stadia Connect was confirmed for Thursday and Larian Studios teased Baldur’s Gate 3 in the code of their website.
If the information is correct, it means that Baldur’s Gate 3 will be available on Stadia. It might even be exclusive to the platform, but that is less likely. We will have to wait for Thursday to find out for sure.
