I remember discussing here with 3dilletante which knows a lot more than I do on those matters about the odds about having for example a power7 and power a2 cores in the same chip a bit like the small/big ARM a15 and a7 philosophy.
He told me that actually the powe7 and power a2 may have slight difference in implementation of the ISA that could hinder the implementation. The A15 and A7 were developed hand in hand.
Looking at Nintendo I think it's unlikely, putting together a CPU is complex and costly enough, 2...
The whole thing sound like quiet an expanse.
Honestly I still believe that the best bang for buck would have been a redesigned Cell (like a cut power7 + 3/4 SPUs). Either way using low power cores and a SMP set up they could have gone with more cores (like 6/8).
To me the best system with their high constrains (cost and power) would have been sonething like that:
Cell 2 Power7 + 3/4 SPu, would end barely above 100 sq.mm on IBM 45nm process.
A ~redwood (so 4/5 SIMD) including 16MB of scratch pad 9edram) memory on the same process (around the size of MS vahalla chip?).
the gpu is the north bridge, 1 or 2 gb of ddr3.
We are going to find out soon how much silicon Nintendo invested on WiiU, that's gonna prove interesting.
What's trying to be a bunch of presentations

Tuned EADGCF and liking it :)
