In an unexpected move Stadia Base has launched. This comes of after xCloud expanded the number of regions it is now available. With Stadia anyone in the 14 supported countries can join Stadia and get 2 months of Stadia Pro. Current members of Stadia Pro have had their Stadia Pro subscription extended for two months.
The full blog post is found here. The rollout is happening over the next 48 hours so if it is not available in your region you should try back every so often.
This is a big move for Stadia and should increase the numbers playing on Stadia and should increase the playerbase for multiplayer games as well,
