No. IBM is only planning to produce a single 90 nm G5 chip, period. Thus, Apple can choose to put this one chip into a laptop or a desktop (only one). I imagine this desktop (or laptop) will be quite expensive since it will have a limited production run (one unit!!!).
You know, only 5% of people will realize this is a joke. ;-)

Well, we have no idea what a .09 micron 970 will take to run. It is rumored to have enhanced powersaving features. I'd have to agree though.. the 7457 is a very low power CPU. Also, other vendors are having serious issues with current leakage w/ thier .09 micron processes. This is [one reason] why the .09 micron Prescott will generate MORE heat than the .13 micron P4. As a Physicist told me last week.. "quantum mechanics is for real".
Just in case it didn't occur to anyone.. there isn't a compelling reason to move to 64bit in a laptop at this time.
You can't put a significant amount of memory in a laptop so you don't need large memory addressing. The only reason for 64 bit-ed-ness would be super high precision integer math... and not many people actually need that (encryption/decryption are the only common tasks that come to mind).
The only compelling reason to put a PPC 970 in an apple laptop is because it's a better processor than a G4.
Motorola has been promising a G4 7457PM processor for a while now. Everyone knows how Moto blows promises regarding cpus, but they were promising a DDR FSB version of the G4 that clocked up to 2GHz at ultra low power... and they promised it in the 4th quarter of 2003.
It isn't beyond the realm of posibility that Moto could actually deliver one last G4 revision to Apple. If Apple could get a G4 with a DDR FSB, and a clock of between 1.5 and 2GHz, it would be a very competitive portable CPU.. and it would likely have excellent power characteristics since wattage has been Moto's main goal with their PPCs for a long time now.
If it's in development, and Moto can deliver it, Apple would probably be better off sticking with the G4 for a while... at least till they can evaluate the G3s w/ Altivec.. or low power 970s more.
Heck, now that iBooks have G4s, maybe we'll see next gen G4s in Powerbooks, and then later next year.. G5 Powerbooks and G4 iBooks.
