seeing that the specs are so close right now I don't see how apple could possibly update the ibook before the next powerbook revision. Here's what I'm thinking:
12' ibook (999):
1.42 ghz G4
384 SD RAM
Geforce FX 5200 go
40 gb 4200 HD
combo drive
14' ibook (1299):
1.5 ghz G4
512 mb RAM
Geforce FX 5200 go
80 gb 4200 HD
Superdrive
12' powerbook (1499):
1.67 ghz G4
512 mb RAM
Radeon 9700 64 mb
80 gb 5400 HD
superdrive
bluetooth 2.0
15' powerbook (1999)
1.8 ghz G4
512 mb RAM
Radeon 9700 128 mb
80 gb 5400 HD
dual layer superdrive
bluetooth 2.0
17' powerbook
1.8 ghz G4
1024 mb sd RAM
Radeon 9700 128 mb
120 gb 5400 HD
dual layer superdrive
bluetooth 2.0
150-200 mhz jumps across the board, plus coreimage-compatible GPU's. There would also be enough of a difference in the 14' ibook and 12' powerbook (for which superdrive is now standard) to justify the extra $200.
