PowerBooks - 13", 15", 17" versions. All will be widescreen HD. All will have either freescale dual-core g4 (probably most likely) or single core g5.

This will be a major upgrade to every single line and will allow the PPC to go out with a bang before intels start coming. Oh and these models will all lose their G* designations. As of these models apple will introduce some kind of new naming scheme in preparation for intels. It is very possible that there will be no specification at all other than "iMac," "PowerMac," etc.
