Your max is a little off. Broadway runs a 723 MHz. Assuming your 32 times slow statement is corret, If it was upped to 3 core then it would only need to run at 2 MHz to match the xenos. 2.5 would put it ahead.

Wait a seccond that doesn't sound right, each Xenon core should obliterate the Broadway at the same clock, it has a SIMD: VMX128 with 2× (128×128 bit) registers and SMT capabilities, plus a more modern instruction set.
The actual numbers are 2.9 Gflops for Broadway at 729 MHz (the reported clock of the Wii). 76.8 GFLOPS for the Xenon so ~26X faster in terms of flops. So Xenon 25.6GFlops per core at 3.2GHZ is over 8.8X faster than the Wii's Broadway at 729Mhz in terms of raw Flops so wouldn't each Broadway core wouldn't it have to be clocked at 6.435GHz to match it with tri core vs tri core?
But I don't think anyone is suggesting that it's just 3 overclocked Broadway cores.

Making it 3 cores would make the performance 9 Gflops at 729 mhb. Triple the power and tha twould be 27 Gflop at 2.2 Ghz.
Also, to make this three core it would clearly have to have major arhictectural redesigns which would mean larger/faster registers and a larger/faster cache as well as a more enhanced veloctiy engine features along the lines of SSSE3 or whatnot.
We still have cofirmation of it being Power7 based so its reasonable to assume that is the Broadway Architecture with Power7 features.

Like I said Xenon is 25.6GFlops per core, it's 76.8GFlops total...
So yea 3 Broadway cores at 2.2GHz is only faster than 1 Xenon core.

Where did you see that is 25.6 per core?
Also, you are neglecting the other facts I pointed out(enhancements from modern tech).
