What we know so far; Play station 5 may come after all?

Cerny as he did with PS4, acted as lead system architect for the new ps5 system. Cerny plans to integrate devs’ wishes and his own gaming hopes into something that’s much more revolution than evolution. For 91.6 million consoles that people play on and 876 million games sold that's good news indeed. Play station's got a brand-new box.

Cerny plans to have;
A movie like experience with 3d audio / surround sound
Faster stronger system
Faster load times
Better visuals
New CPU new gpu
Maybe a new psvr unlikely at this time since the Current Vr seems to work just fine
Larger and larger sizes for games. example; red dead redemption 2 at 99 gb 
And the game changer; new hard drive a solid state drive 
Will support 8k graphics currently only 4k tv's
Backward compatible with ps4
Cloud gaming (which Goggle [Spoiler; if you have not watched wreck it Ralph 2 you will not get the joke] is already working on
