Im sensing that this is a joke thread in response to something else, but I mean its already happening. PS Now can be used on PC, and some PS4 games are coming to PS Now.
Sony's end game for this is the Netflix model. They want every single device under the sun to come with the PS Now app installed by default (or install-able from the marketplace) and able to pair with a 'DualShock Now' or whatever it will be called controller.
I'm not sure what you would call this. I think that their games will stay first party to their apps, but their apps will go third party on many platforms. So essentially you won't need Sony hardware to play them, but you will need a Sony subscription (same as Netflix). You could think of the first party games the same as you do 'Netflix Originals'.
