Already watching sites trying to squish the xbox leaks news to talk about the possibility of PS Studios games being available on xbox if it has Steam integrated.
Just remember one thing guys, many years ago a streaming service was launched to play your Steam games from the browser (when and how it's called I don't remember because I don't play on pc lol but I think it was a NVIDIA product). Many people were talking about how you would be able to play God of War on xbox and how PS wasn't necessary anymore etc etc. What end up happening? ALL PS Studios were were blocked with the obvious exception of Death Stranding (at that time Death Stranding was still under the consideration of being a "PS game").
What is going to happen now? Sony will most likely talk to Valve to block their games on xbox consoles even if the consoles have a native Steam app. That's all.
