Some interesting tidbits in this new article …

The next Playstation - in a surprise move - will be called Playstation 5!
They confirm that the ray tracing support is hardware based in the GPU.
They talked and demo’ed new dualshock 5 (name to be confirmed) - with programmable resistance in the triggers and better haptic feedback all round. The opportunities for this are really nice, simulating a bow draw by making it hard the further back you draw and making a shotgun feel different to an AR.
They also talked about UI changes and being able to launch straight into different parts of a game from the UI. That sounds like a good QoL update even though game launching should be super quick anyway.
