I still can't understand why they based the PS5 around the PS4... the PS4 is getting more and more hacked as the days go on! to me it's like them building the PS4 around the PS3... it would of been a huge mistake.

Yes the PS3 was MUCH easier, but devs have shown Sony the PS4 is not very secure, harder than PS3 yes... but its still open for devs.


It's nearly impossible for $ony to change the Core OS they use which is (FreeBSD), because that mean a long new journey for devs to learn and use the new OS and tools, which means a lot of money for $ony to pay for studios and devs, also if $ony made new OS from scratch, then they have to check all security weakness and vulnerabilities in their new OS by themselves, it's better for them to rely on experience third party for stuff related to security.

Most of the time the vulnerabilities are found in things $ony don't have control on it, like IP4/IP6 protocol and browser webkit, which is part of FreeBSD OS.


On the one side, I want update my PS5 for the Matrix Tech Demo, on the other hand, I want some jucy exploit on 4.0.3
