I'd hoped this would regard improving gaming on Android devices, maybe releasing a controller that all devs will implement rather than relying on touch screen controls.
I already have a controller that attaches to my S9+ and makes it a really nifty handheld console on the games that actually support it, problem is many games don't even allow proper controls. EG Street Fighter 4 is awesome on Android with a real controller, Tekken doesn't even support it.
This new streaming service smacks of them ignoring their existing major user base to try create new revenue streams that I just don't think will exist.
Casual gamers will continue to play free to play games on their phones, hardcore games will continue to want to own their games outright.
I'll be happy to be proved wrong, but I'm predicting very little success for this in an already crowded gaming market.
Also, many associate streaming with dropped connections and low quality performance, whether that's true or not they'll have a very hard time gaining market share with this.
