The only information we have so far is:
"And in 2020, more games will come to Stadia, including Doom: Eternal, WatchDogs: Legion, Gods & Monsters and Cyberpunk 2077. " Source: Google Blog
But there is no Roadmap, which games are coming first or even when they are coming, so I guess we can just wait. Most games are not even released yet anyway (even not for other platforms), because they are still in development.
A full list of released and planned games you can find here.
