I wouldn't expect CPU upgrades. However, i do think they'll move to the serial standard of PCI-express. They may also up the base ram config (sure as hell needs it) and other little things. I wouldn't expect too much. 3ghz is gonna be over 6 months away. I'd put money on it. A year ago I thought we'd have powerbook G5s and to this day it's still a dream. It's just a slow cycle when you're pinned to a CPU manufacturer that can't get it up
