Stadia is a new Cloud Gaming platform that runs on GCP and details were announced some minutes ago.

For maximum performance you would need at least 35mb/s, while about 10mb/s are enough for 720p l, Stereo gameplay.

Maximum performance provides 4k, HDR and 5.1 Surround Sound and comes in at 9,99$ / month for Stadia Pro. As far as announcements go, there are no lower performance tiers available.

Stadia Pro will get you unlimited access to your Games (I believe this is Bring-Your-Own-License, but I might be wrong), while Stadia Basic allows unlimited access to one specific game. For that you probably buy the game directly of Stadia, which then includes any fees in it's price.

Stadia will be usable on all devices that run Chrome and on the Chromecast Ultra. Android will get it's own app, first available on the Google Pixel 3, to be expanded later on, iOS was not mentioned.

Google developed a custom Stadia controller that works out of the box, including an Google Assistant and a DVR button. However, all other controllers should supported too, but I don't believe that's the case for playing on the Chromecast Ultra.

Starting now, you can get the Stadia Founders Edition, that allows you to be one of the firsts on the platform, includes a Controller, a Chromecast Ultra, 3 months of Stadia Pro, 3 additional months of Pro you can gift to your buddy and some Destiny Bundle with the first and second game, including all add-ons, plus the Destiny 2 Season pass.
The founders edition can be pre-ordered right now for about 129$.

Stadia launches 'later' this year, founders edition buyers will be the first to get public access on launch.
