Ok people, lets get it straight.
Apple and Motorola are basically finished. Motorola can't product processors well at all. They are the reason apple has been behind in clock speed for over half a decade. Now this update probably won't be to G5s, but it IS the end of the line for G4 powerbooks.
Why do I say this? G4s run hot in powerbooks. Granted the 12" problems in heat ARE NOT from the CPU, but from the hard drive and power board. The G5 was in development for a while, and I bet apple has a G5 laptop. It wouldn't be hard to impliment a G5 laptop at this point.
Look at it this way. the powerbooks have DDR (except for the 15") right now, but can the G4 take advantage of DDR ram? NO it can't, and since theres DDR channels already on the boards how hard would it be to put a DDR aware CPU on, new controlers andan ATA bus? Not very in my oppinion. The G5 at 1GHZ and with a DDR 2700 bus would be PREFECT for a low heat, damn quick laptop.
All of you saying the 17" will get a G5 and the rest G4s dream on.

Why would Apple do that? It makes no sense at all! Dual G4s maybe, but a G5 in one model and not the others? No way would Apple do that. The 12" is their best seller for a reason.
All that said... Tuesday probably won't bring G5 powerbooks, but I would not be suprised if it did. We have waited a long time, and there has to be something huge in the pipeline. I guess we have to wait it out...
