Calling Cell a PowerPC is a bit of a stretch. The only reason to use the Cell was the SPEs, which had their own custom SIMD instruction sets. The PowerPC core was just there for coordination.

Any work you put in to optimizing your code for the Cell would be completely thrown out if you brought it to another POWER architecture. At that point you might as well have hopped over to x86, ARM, CUDA, Xeon Phi, the Connection Machine, whatever.
