I wonder how they want to achieve that. Perhaps with a standard upscaler. No way it will render existing games in 4k natively.

That's 1000% more likely.
A slim version with HDMI 2.0 port and upscaler to output all content in 4K. Just like the 360 upscaled everything to 1080p last gen. These 4K upscalers have been in blu-ray players for a couple years now, easy to add. Someone simply misunderstood what they were overhearing. Rendering console games in 4K is a long way off.

I'm hoping that that's all this is, if it isn't actually PS5 they are talking about.  If it's just an improved model, Slim or not, that would be just like the PS2+.  It just added support for a few video formats, as well as upgraded the DVD player to a progressive scan one.
