A recent report from Kotaku claims two unnamed developers spoke with them citing that they had knowledge of Sony’s plans for a new system, with both saying the system won’t come out until 2019 at the earliest. “At some point, Sony’s probably looked at every possible date. It’s all about what they think is the best sweet spot in terms of hardware,” one source said.
Rumours have suggested that Sony has given PlayStation 5 “devkits” to some studios. Devkits could take the form of a PC with a test version of the CPU and GPU of the end product. Kotaku’s report also says that Sony, in the past, has asked studios to keep the devkits in locked rooms with restricted access to only a small number of people; even developers at Sony’s internal studios had no knowledge of a new PlayStation console.
It seems the soonest we will see anything of Sony’s new hardware will be in June at this year’s E3 conference.
