A G5 powerbook would be a major upgrade which will most probably come along with a new case design. I would lie if I say I am not hardly waiting for it. I don't believe there will be an increase in speed toward the current G4 chips as less as I believe it will run as hot as many in this forum think. It wouldn't take ibm or apple so much time to release a G5 in the powerbooks if they were planing to picked the desktop chips. Beside that I would be very curious how they will connect the memory to the system and how the higher fsb (if at all) will influence the system and also if we'll finally get a dual layer burner in the books and a hdtv accelerating graphic unit.
So, I think most of the ppl are not so much curious about the G5 chip in the upcoming powerbooks but rather what will be included in this major update. We all know how the G5s perform and that they are not so roughly outperforming current G4 systems (Mac Mini vs. iMac G5).
