This PS5 design Incorporates the benefits of hi-fiber networking for non-local processing power, rt-superconductors and haptic holographic technology to deliver an exclusive gaming encounter. This kind of stuff may sound like science fiction, but it's not outside the realm of possibility.
A company called Looking Glass has already been working on holographic displays. They are joined by another recent contender called Holovect which launched their product on Kickstarter. Their focus is currently on "volumetric vector images."
The difference right now, is that Looking Glass creates images within a box, while Holovect creates free-floating images in the air. While these don't represent the kind of holograms shown in these concept images, they are the beginnings of technology like this.
