That is an incorrect statement. The research papers on Cell and it's use in medical equipment, Military radar systems and in the fastest computer in the world supports the cell in 2005-2008 was the most advanced CPU for certain use cases. Because IC design hit a physics wall the industry has turned to hundreds of CPUs at slower clock speeds exceeding a few highly clocked CPUs at power efficiency/heat generation which limits the number of faster CPUs in a package. Heat is the enemy and any efficiency both in physical design and programming is needed in next generation Game consoles.Dude...let go of the dream of another Cell-powered device. It was a complete and total failure...why in the hell would they keep dumping money into R&D on a CPU that nobody wants to use, is more expensive, and doesn't have a noticeable bump in graphics compared to their competitors?
As far as BC is concerned, I think your best hope is that they go through the trouble of porting the PStore titles to avoid problems but disc-based games will likely not be supported.
All IMO, of course...
A few SPUs could be used or a few X86 CPUs or a combination but because of their high clock speeds they are inefficient and generate heat. So a few fast CPUs and hundreds of slower GPU elements that are modeled from Cell prototype designs ideas are used for next generation CPU and a separate dedicated GPU for either heat issues or to separate function when needed due to memory bandwidth.
The above was recognized by IBM in 2008 and IBM turned to AMD for their GPUs. In 2007-2008 IBM was testing Nvidia GPUs (running CUDA) against Cell and developed a OpenCL library for the Cell processor and because Nvidia (my opinion) would not release anything but CUDA to support their GPUs, IBM turned to AMD. By 2010 IBM dropped Cell in favor of GPUs and OpenCL. Sony could still have used a 24 SPU chip clocked lower than the PS3's Cell 3.2Ghz and used eDRAM in the same package and it would have been close to the same functionality of the current AMD APU rumored in the PS4. I'm guessing the AMD roadmap both design efficiency and features as well as production costs had Sony going with AMD.
