I think the distinction is more than just cores-per-die,
but rather that VFB's authors coin manycore as the approach
which embraces all their hot-buttons (low-power, fairly dumb cores,
lots of them, no coherency among them, some kind of virtualization,
thin OS's, autotuning, etc.)

cell-BE is a PPC with some attached processors.  it's not that 
much different from a cpu+gpu (not surprising, considering its market.)
