The SteamDB website has been updated with a hint of a service called Steam Cloud Gaming. Among the lines, we found references to online agreements and standard messages about errors and notifications.
For example, there is a line that says the following:
Thank you for signing the Steam Cloud Gaming agreement.
However, it’s just code that hasn’t even reached Valve’s partners yet, and it will go through some changes in the future, as is usually the case when early and unconfirmed data leaks into the network. The company may be working on cloud streaming technology to fight Stadia and xCloud. The technology may be introduced into the Steam client next year.
We are looking forward to the official announcement from Valve.
