I was trying to think what Sony brought to gaming with PS3...
Bluray
Chargable controllers
...
.....
HOME, I guess...
Help me out. Games excluded. OS, services and hardware only.
I was trying to think what a PS4 would be? Aside from MOAR PoWERZ. And, you know, it was kind of hard to see much innovation by way of PS3 imho. And I look at Sony's tablet attempts, Xperia, the PlayStation Suite, Vita OS, PSN, SEN or whatever it's called tomorrow...It's pretty clear they don't know what they're doing. You have to hope their 1st parties are advising them. I suspect prior to Kaz, Japan likely wouldnt have given two shits what Naughty Dog thought about how to turn PS4 into a winner. I hope in a Kaz World, the opposite rings truer.
A few off the top of my head. There are probably more...
* Blu-ray for next gen and next next gen storage
* Renewed effort in 3D gaming
* Playstation Suite çan actually be interesting, depending on how Sony play their cards
* Open standards (HDD, OtherOS)
* Free online gaming
* EyeToy, PSEye
* RemotePlay
* MLAA, plus all the cool tech sharing with developers
