This sounds like fun! Maybe we could have a sweepstake!
- 12" model will have 1.5GHz G4, 14" model will have 1.67GHz G4. Both will have 167MHz FSB.
- 512Mb standard. Probably all soldered onto the motherboard, leaving the second slot free, but I wouldn't bet on this.
- 12" model will have 40Gb hard drive, 14" model will have 80Gb.
- Some sort of video hardware upgrade. I don't have enough knowledge in this area to be specific, but I think it would be fair to assume that it will have 64Mb VRAM and support core image.
- An increase in display resolution and Superdrives across the line are possible, although I'm a bit less confident on these aspects.
- Built in bluetooth.
- Price drop of $US100 - 200.
- No change in form factor (even though it's overdue, they will wait for the Intel units before doing this).
If you're thinking that these specs are too close to the Powerbook, please bear in mind that I believe that the Powerbook will be updated at the same time. In terms of timing, I think that we'll be looking at Macworld Paris, or shortly after.
