By the time the Scorpio comes out there will be well over 70 million(probably more) PS4 units out there, of which probably 5 million PS4 Pro units sold. Also given that the checkerboard up-rendering is supposedly patented by Sony and is built into the hardware and makes it quite easy for developers, the Scorpio might be harder to program and design for compared to the PS4P and might take more work. Digital Foundry were very impressed with the up-rendering of the PS4P and they are known to be quite tough on their viewings, so the different between the Scorpio and Pro might not be as huge as the Teraflop advantage may have us believe. The up-rendering technique doesn't seem to be too taxing on the GPU itself, where native 4K needs essentially 4 times the amount of pixels as 1080P.
