Well... my last bold prediction didn't go too well, but I think this one is it!
I believe the PS5 will be the last time sony ULLY hits the reset button when gong onto a new generation. So the PS6 will be pretty much just like a PS5pro. And I expect it to come along in around 5 - 6 years.
The PS6 will become the 4K console, and the PS5 would at that time become t 1440p+ reconstruction or even just flat out 1080p console. In 6 years, we could very well be having a PS6 that would be packing 40TF GPU, that's just 4x more powerful GPU wise than the PS5. And I believe at that point sony would release every game across both the PS5 and PS6, but the PS5 would just become a 1080p console.
This way, PS5 would e supported fully into the tail end of the PS6 life, and would only stop being supported when the PS7 is released. So something like this.
- PS5 + PS6 = cross compatible (full softwaresupport)
- PS6 + PS7 = cross-compatible (full software support, PS5 software, and hardware support discontinued)
- PS7 + PS8 = cross-compatible (full software support, PS6 software and hardware discontinued)
This way, sony would never start any new-gen from zero again, and the install base will steadily continue to rise. When PS6 comes along, a lot of people wanting to get the latest and greatest could just pas on their PS5s in the used market, and those consoles remain active and maintain full support for the entire lie of the PS6. Then people that didn't jump in on the PS6 from the PS5 can get the PS7..etc.
