I really do think that any updates to the 'Power' range are very unlikely at this stage, otherwise they would have been announced at the keynote at WWDC. As it was, the whole expo was dominated by the move to Intel and as such, did not really leave anyone with a clear roadmap for the interim period until new Powermacs are expected to be released in a couple of years time. Steve Jobs has said that PPC is not dead yet and that Apple does still have a couple of tricks up it's sleave, but it would have been great to have been able to see them launched at WWDC. The fact that they weren't makes me think that we'll have to wait considerably longer for the next updates to both Powermacs and Powerbooks.
