The date was what they originally had planned, and it is quite obvious now that those plans have changed.
They stated at GDC that it was too soon to talk about the next generation hardware or software.
as for the 3 processors, I know they have been talked about b4 but I didn't expect 3 3.5ghz PPC (G5) chips
especially since I don't even think apple has G5's at 3.5 ghz yet. How would they be able to put 3 of those in their machinr next year and keep the price affordable?
