- Cool and quite form factor
- Faster BD drive, but not too high RPM so that noise is a factor, maybe 4x?
- BC with PS3 and PSN games. Keep the PSN free, not paying for P2P
- $299 launch price for base model
- Fully supports Move hardware for PS3 and PS4 games
This is a very good list. Let me add[*] USB 3[*] Updated PS Eye (optional) with depth tracking and better resolution/framerate
I'd be OK with a $350 or $400 initial price tag, if the machine had the grunt to justify it.
I really shake my head when I see rumors that Sony is considering ditching the Cell for PS4. If you are starting from scratch and going for a blue-sky design, Cell is probably not the best answer. But when you have all the existing dev tools, already-built game engines and modules, Home, and all the Netflix etc. media apps already written for Cell, to not use an updated version of the chip that is completely or nearly bit-compatible would be off the charts insane.
Sony needs to "pull a Wii" for the PS4. Most people think of that phrase as meaning underpowered and cheap. But the most important part of the Wii design was that it was architecturally compatible with GC. More important than the low price, the motion gimmick, or anything else, was that all their devs already knew the architecture, and were able to write compelling software for it early in the console cycle.
But compared to Nintendo's position back then, a Cell-based PS4 does not really need to be underpowered compared to the competition. Sony invested a lot into the architecture, and if there's half a brain among their management, they reap the benefits next gen by extending it, not jumping off to the next "hot" CPU design.
