It's not a good desktop CPU, it's designed for consoles. Then I do not think Toshiba (since they bought Sony's share of cell production) is selling it to anyone else but Sony. So unless IBM is producing new cores to keep up with x86_64 multi cores, Freescale and others are going to keep repackaging the cores they have licenses for. Freescale is pushing ARM for a reason. ;-)
Freescale just recently released the brand new e5500 core.
Nobody is pushing ARM for anything other than mobile devices.
