Quick Summary of Playstation 5 article:
-Uses AMD's Navi as its base architecture, not specifically using Navi.
-CPU is custom Zen
-Large amount of devkits have apparently gone out.
-Author suggests 2018 release of PS5 is not out of the question based on the amount of devkits released as this is a "sure sign that the launch is getting close". Not definitive.
-VR "goodies" baked in at the silicon level. (My Opinion, not authors: Sony not giving up on PSVR any time soon. VR support inside the PS5 right out of the box)
Semiaccurate is pretty legit. They leaked info on the PS4 and XBO in 2012/2011 and leaked spme info on the switch. I dont think its coming this year but based on this information i think its going to come out next year.
