Probably not
y'all should take a look at this article.
http://maccentral.macworld.com/news/0112/04.motorola.php
it was written on december 4th (my mom's birthday!), so there's a chance that things could have changed between now and then, but probably not. for those of you who don't feel like looking, here's the basic point, quoted from the article:
"Motorola has already announced many G5 processor products -- the MPC 8540 in the networking space, announced at this year's Microprocessor Forum and the MPC5500 family in the automotive space, announced October 1, 2001. The MPC 8540 is one of the first G5 products to be announced and will be sampling in the first half of 2002, according to Motorola's Microprocessor Forum presentation. None of these G5 processors have all of the necessary components to be used by Apple on the desktop."
look, i want to see and own a G5 as much as the rest of you, and 2002 is almost certainly the year for it, but 2002 is only 5 days old and the G5 isn't ready for the mac quite yet. but damn, i know they're going to blow us away nonetheless.
