No PowerBook G5 until next year, but refreshed G4 sometime soon?

Now that the iMac has gone all G5 on us the Apple faithful (and, well, the not so Apple faithful, too) have been asking: When the freak is the PowerBook G5 going to arrive? Plenty of people at Apple have been trying to
dampen expectations that one will be out anytime soon,
but PowerPage reports that while they're definitely hard at work trying to get the cooling system down (the G5 processor runs so hot that putting it in a PowerBook could literally be dangerous), that Apple is probably going to refresh the G4 PowerBook with faster processors (1.8GHz and 2.0GHz) and a new fan system before they take things to the next level. So basically that means no PowerBook G5 until probably March of next year (though a January surprise timed for the release of Tiger—aka Mac OS 10.4—is possible) but refreshed G4s should be out sometime within the next few months.
