I think its a guess that hopefully comes true that he can claim as the insider that broke it. If it doesn't come out they can say that due to the ship shortage they decided not to do it.
It's an easy guess really. Let me see if I can do it.
CPU - Zen 3, 8 Core 16 thread @4.1-4.3ghz. Variable (I think this has worked out for Sony)
GPU - RDNA 3, 72CU @ 2.2-2.4ghz.
18-20 GB GDDR6 RAM @
1tb NVME SSD at the same speed as the PS5. No need to increase it at this point.
I mean, we know that Sony's BC relies on the number of CUs for ease of compatibility, so why change a formula that has worked for them.
They won't add too many functions like Mesh Shaders, VRS etc as the pro needs to be a similar platform as the OG PS5. The next gen will introduce those additional functions.
Having said that, once the rumours come out about the Pro models being made it's about 2 years before we actually see them, making it around Nov 24 release.
