With both Xbox and PlayStation consoles receiving receiving proper 4K treatment within the last two years, Sony fans may have to hold out just a bit longer until 2020 for another major console release.
According to Kotaku’s sources, both third party and Sony’s first-party studios close to the gaming blog, have not received any concrete evidence or briefings indicating that the PS5 (or whatever they plan to call it) will be released any time soon (2018 or 2019). Two sources familiar with product development were able to say that fans should not expect a new console until 2020 or beyond. They also said that games being developed for this console will not be compatible with the PS4 consoles.
However, they made note that nothing is final and the release timeline could significantly change depending on market conditions and if other major competitors decide to make first move on releasing a next-gen console within the next year or so (even though it is unlikely).
The 2020 timeline goes against an article posted on SemiAccurate. They claim that a large number of PS5 related devkits were sent out to various studios and other developers, indicating that a new next-gen console may not be too far away, and even hinted at a late 2018 release date.
However, as Kotaku rightly points out, there are different versions of devkits, and the very early versions may simply be a custom-built tower with proprietary software to help game developers understand the technical capabilities of the next-gen console. It may only be good to help them develop a roadmap towards development, which could then take place when more advanced devkits are released.
Devkits are usually a well-kept secret, and Kotaku themselves stated that no studios have hinted to them yet as to whether they were in possession of devkits for the PS5.
