Lo que Goto dice haber oído de sus fuentes:
* The number of CPU cores in PS4 is still undecided. SCE is waiting for feedbacks from game developers. The CPU design is not yet frozen and it's still in the research phase. However Goto often hears rumors that SCE is going to take a cautious route for PS4.
* There is a plan that PS4 uses a generic JEDEC-standard RAM for the cost reason. (According to Goto, if SCE really takes this plan, low-energy DDR3 will be the only possible choice for PS4 due to the effective cancellation of DDR4.) But SCE is evaluating DRAM 3D stacking or packaging in CPU.
* Currently few SCE engineers are at the STI Design Center.
* Some game developers think the Cell architecture has to be fundamentally modified to make its learning curve less steep
Pura especulación por parte de Goto (que a veces acierta y a veces no como todos los analistas):
* Cores in PS4's CPU will be 10+. If it's at 45nm it will be 150mm2 or smaller. The performance jump over PS3 will be 2.x times at best.
* SCE has to pursue low development cost and low manufacturing cost like Wii. So PS4 will be released in 2011 unlike previous speculations that this hardware generation allows incremental hardware/software updates in a longer span than the previous generation. The only option that makes the 2011 launch possible is to refine the current architecture.
* SCE has to stick to the Cell architecture because of the already spent development cost. The local store architecture removes the need of a coherency mechanism that hinders adding CPU cores. Also SCE predicted most of future workload will be stream processing that deals with hardly recycled data where the merit of a cache is no more than a read-ahead buffer. A portable memory space in LS suits distributed computing. It's natural that SCE tries to expand the Cell architecture in the PS4 generation since scalability is Cell's strength. After mentioning the rumor about the STI Design Center and the possibility that SCE abandons the Cell architecture, Goto speculates SCE engineers will return to Cell development after completing the research to decide the PS4 concept.
* PS4's software assets will be inherited from PS3. Though it is said that some game developers think the steep learning curve is inherent in the Cell architecture, more fine-grain software objects and more CPU cores can make the current issues less troublesome.
* Though it seems SCE is contemplating a modest PS4 plan not to repeat the PS3 launch missteps, a too modest hardware spec for PS4 can't differentiate it from the current generation and may lead to a launch failure like PS3. If it's as modest as alleged, it's important to add appealing features not in the hardware spec just like Wii.
