Someone might be interested about 64-bit PPC rumors:
"Q: I noticed late last year there were a lot of rumors circulating about the G5 but I haven't heard much recently, do you know what the current / rumored time frame for the G5 is?
A:
Just take one look at Steve Jobs' statements from the recent press-restricted shareholder meeting, and you'll get the answer: "we have some pretty good things coming."
In Steve-speak, we're led to believe that this means: we're not going to trample all over the performance issue in one fell swoop, but we're going to continue to come out with systems that widen the gap in certain areas, and catch up in others. In short, the G4 has legs and will move to 1.6GHz+ in the year ahead, along with 400-500MHz high-bandwidth memory. But for those seeking the G5....expect to wait a little longer. It may also not be the processor we are expecting....unless of course Apple passes off the new high-bandwidth G4s as "G5"s."
