Given what we know now. I think it's more likely that the Wii U's CPU is a modified Power PC 476FP. Same family as the 750. Except it's already manufactured at 45nm. It would be cheaper for Nintendo to have the 476FP modified than the other way around.

That's the one part that was confusing me. IBM said they had no intention of going below 90nm for hthe 750 and we know WiiU is 45nm. I figured since Nintendo was paying they did it anyways. Hopefully more info will come out to clarify it further.

Not only that, the 750 core was never designed for a multi-CPU setup. The 476FP was however.
