But c'mon, cell is gonna be old as hell at the time. Lets hope they'll use optic processors or something. Is that the only new processor tech underway, accept maybe quantum computers?
IBM et al continue to refine their methods. Cell today will be old as hell, but Cell in 2011-2012 will be 'new' and different from what we have today, benefitting from the years of development and process improvement.
There were a couple of announcements in recent months by IBM that seemed to be well timed for a PS4 kind of timeframe, like chip stacking for example. And STI are now researching at a lower more fundamental level than before, undoubtedly seeking to incorporate new lower-level techniques into future Cell chips.
I think nVidia as a GPU partner is a good bet. Whether it'll be a PC variant or something more custom than RSX was, I'd be hesitant to say. They should have time on their side for a more custom approach this time around, but costs may encourage them to leverage existing nVidia product more heavily also (and I think cost will be more on their mind with PS4).
BD should buy them a significant reduction of losses vs PS3, as mentioned, of course.
I think, though, one major thing I want to see them focus on for PS4 is the readiness of the software platform from day one. They need to build and extend on what they'll have from PS3 rather than throw out and start again. I'll SCREAM if we have to go through another cycle of incremental updates, waiting for download managers and friends lists
And I'm sure on the developer side, they'd scream too if they're back to square one.
I'm slightly hopeful for something more radical on the interface side of things. I was kind of surprised that a new kind of eyetoy wasn't standard in PS3 (although not so much when the realities of the cost of the rest of the system came to light).
I think though, in general, there's going to be a lot of discussion at Sony over strategy for PS4, and it's hard to say for sure what the outcome of that might be from a technical perspective.
