There are some persistent rumors that Sony will release an upgraded PS4 version with 4k capabilities soon. While I am not opposed to the idea myself, I am wondering if there is any possible way Sony could pull this off without alienating and splitting their PS4 user base. Perhaps if all future games automatically scale to the given system, and provide 1080p for old PS4s and 4k for the new version? Full cross compatibility would be a must, I think. But would devs be happy about the extra work of providing two different resolution outputs depending on the system? Would games run slower on the old models? And would users who just bought a PS4 be happy that their console just became outdated? Maybe Sony can offer some kind of trade-in / upgrade plan for existing users. I guess if they do it smart, it could work, but it's quite a gamble. Really curious to see how this plays out.
