Actually, they did, because both the PS2 and PS3 were extremely complex.

It took Kazuo Hirai stepping in as CEO to have enough influence (which Howard Stringer never had) to fix ego issues in the Sony hardware engineers group. Made them more consumer focused by making them pass the test on each idea of whether it is something beneficial for the end consumer (developer/customer) or just something that will be cool for them as engineers. Plus Kaz made software/services person (Mark Cerny) in charge of design priorities retiring the father of Playstation (Ken Kutaragi).

The PS4 is a dream. A culmination of all the things they learned about what they did wrong with PS3 when they tried to update it to have feature & performance parity with Xbox 360, plus all the consumer (developer/customer) feedback.

The most genius part of PS4 design is that they put separate processor and memory all for the OS so system features don’t compete with game features for system resources. This is something I hope MSFT/Nintendo and others will copy and/or improve on going forward.

4 years later… TLOU still = The Last Of Us.

Oh the irony of the future

Years later after this comment… you are right.

They didn’t make the same mistake twice.

I don’t understand your irritation, that was perfectly understandable and in some situations quite witty…

Oh! Sorry, I forgot some people don’t speak computer science…

so ignorant. why the fuck would Sony ignore their biggest mistake this generation?
and fyi the PS3 is selling better than ever, much more than any competitors.

yet another retarded xbox fanboy

Sony are a bunch of arrogant misfits that screw over consumers and lie to cover their backs.
