I'm more interested in the price (and power consumption) relative to the MPC7455, since that impacts the PowerBooks and the iMac.
Yeah, the price is very tantalizing--a high end chip with a low end price. Financially it makes sense for Apple to ditch the G4 and G3, and go entirely with the 970. Apple could easily differentiate products by MHz, Mobo, and dual/single configurations. For laptops, use the 970 in all, but "cripple" it in the iBooks with a lower GHz rating and slower memory bus. In the desktop arena, make the Powermacs all dual, and the consumer products all single CPU, and then use GHz as well to differentiate.
I'm hoping Apple uses this strategy, rather than either using the more expensive G4 and thus jacking up consumer product prices, or using a G3+Altivec. The hacked G3 wouldn't necessarily be bad, especially if it had a new RIO bus or a 970-derived bus that was fast, but a 970 would be even better. However if Apple could acquire very cheap altivec G3s from IBM, then it might be worthwhile to use them in low end macs to keep prices down and margins up.
Power consumption may be an issue, but I don't see this as a reason to stick with Moto. If this fabled G3+Altivec truly exists, then I see absolutely no reason whatsoever to use a Moto G4. None. Moto has proven over and over that they cannot scale their CPUs, and it's time for Apple to cast aside this ball and chain. It would be comically sad if the PPC 970 Macs are at 4 GHz 2 years from now, while the Moto-based low end products are all bogged-down at <2 GHz because Moto can't figure out how to fab anything smaller than 180 nm.
It would be great as far as I'm concerned if Jobs worked it something like this: Moto execs call him up and tell him the 7470 or whatever is finally ready for the Powerbooks, and Jobs tells them, "Great, but we've actually decided to go with a more reliable supplier. But thanks for thinking of us when you designed that chip, it's a very nice gesture. We'll keep you in mind for the future. Bye!".
