Not knowing a whole lot about the G5 architecture, I was curious if anyone knows if...eventually...a G5 CPU upgrade (including dual) will be an option for the Powermac G4 lineup, specifically the MDDs (single and dual)? I saw that Powerlogix has dual G4 upgrades (as fast as 1.4 ghz) but those seem a bit spendy for a processor thats going nowhere fast. Anyone happen to know the product roadmap of G5 upgrades for the current G4 products? Or even care to rumor? Im just hoping at some point, although still far out for me, I can throw a Dual G5 card into my pmac and blaze away! I still remember when I threw a G3 in my pmac 6100 and it was reborn!
