Sony will stop making hardware before Microsoft does.
From the Insomniac leak
Sony is at a crossroads. I'm not going to pretend that Microsoft is fully where they want to be in terms of brand name and marketplace stature but I bet Sony would rather be in Microsoft's shoes vs Microsoft wishing they were in Sony's. Once upon a time, that last part was true but Microsoft is done only focusing on consoles.
Consoles, as much as we love them, are a husk of the industry. Most kids nowadays seemingly want gaming pcs. Even more people play mobile games. Microsoft now has Candy Crush, Hearthstone, Call of Duty and Diablo Immortal and the PC games are day and date. Our children play on our phones before they play on our consoles. What happens when you see the Xbox logo from the age of three on mom or dad's phone playing candy crush? It is almost a conditioning of acceptance.
