I think we are much more likely to see a dual-core G4 than any form of a G5. I do not believe Apple wants to create a Dell-XPS-thin (haha, sooooo thin) notebook for its lineup. The PBooks have always looked great, industry leaders in thinness and overall appearance. If they can get to 1.5" or less with a G5 somehow, they might justify the increased thickness for speed, but who knows.
I bet dcG4 with a different v.card for the 12" at least (get rid of that 5200 already!), more ram support, more stock ram (256 is utterly worthless to most everyone) and perhaps both slots on 12" are user replaceable....COME ON APPLE! that should have been done ages ago. A 12" with 2Gb would rock, you know it would.
dcG4
9700m for 12, 9800m for 15/17
512 standard ram, user upgradable both slots in 12
updated screens, higher res to compete with pc stuff (plus just better)
same casing, similar appearance
perhaps new s.drives, but I could personally care less about that because they will still be slower than an external dual-layer +/-.
Either way, it is Xmas eve here, so Merry Xmas Eve to everyone! (if you are into that sort of thing

)
