The cell processor has been a very successful part of the Playstation 3, able to munch through folding@home as well as the latest HD game demands. There have been many rumours around the net today that the followup to the CPU in the PS3 has been basically 'canned'. The story was that the new Cell Processor which featured two PowerPC processors and 32 SPEs will not be released and that possibly the whole range was going to be discontinued.
We managed to get hold of an IBM spokesperson an hour ago and they said that only one CPU development cycle is being 'halted' which is the successor to the current PowerXCell-8i cpu. IBM have said they are planning to work on other CPU's in the Cell Processor 'family' and we would assume that by the time the Playstation 4 hits market that they could very well be involved on some level.
