To IBM the Cell processor was probably a project that gave them a massive budget from Sony to do (almost) pure research and development; and I don’t think IBM really saw much commercial value in the Cell processor being that they released the Power 6 architecture at (roughly) the same time. At this point IBM has probably gotten everything they wanted from the Cell (hundreds of man years of chip development research on Sony's dime) and without further external funding they probably see no value in continuing developing the processor.
