Sounds like Sony legal team stepped in
We can only guess for now that might be a factor (I guess); if so that does beg the question: why target those leaks in particular? It'd be much more lowkey way of incidentally confirming a rumor by paying any attention to it at all. Other leaks that we know are way off are still floating around for both systems.
So hopefully that wasn't the reason they've been removed, otherwise like I was getting at earlier, that would instantly make them very credible leaks.
Would they really need to do that? its not like the ps4 some complex beats like the ps3 was, they could make a good emulator and be done with it.
You'd be surprised at how lazy these companies can be when it comes to designing their own in-house software emulators. MS is kind of the exception here with the OG Xbox emulation on XBO, but then again OG Xbox emulation was easily the furthest behind in the retro scene so they kind of had no choice. If it were more popular in that scene to get the interest in developing a mature emulator, MS likely would've just taken parts of source code from that and pretend they didn't.
And FWIW Sony had good software emulation in PS3 for PS2; I'll assume that was all in-house and didn't involve any shady stuff. But OTOH, you have situations like Sony's emulation with PS Classic (the emulator isn't actually theirs), or Nintendo being incredibly slow with emulation on their systems (and then ripping off ROMs from the internet to dump on their stores at markup prices), and it's somewhat easy for these companies to take the lazy route at times, even for big affairs.
Also while I'm sure overall PS5 is going to be magnitudes more powerful than PS3 in every single respect, the Cell processor is still a bit of a wild beast. There's some decent PS3 emulation on PC but you need some pretty powerful rigs to get satisfying performance out of it. And we already know neither PS5 or XSEX aren't going to match, say, a 7th-gen i5 or i7 in CPU power.
But outside of that, I'm still curious myself why BC would (allegedly) gut PS5 that much on CU count. Someone else mentioned maybe it's their RT solution being the issue (and if I can throw in there, maybe custom VR support too); that sounds at least (if not more) likely the reason...
...again assuming these latest leaks turn out to be true.
