I have a few ideas of what is going down at MWSF. These ideas seem the most logical for Apple to do: I think if new iMacs come out, they will come with G3's on the low end, and a G4 on the high end. My theory is this: Why would Apple take G4 to or near it's limits if it's ultimate goals is to put the G4 in a desktop model? They have to leave room for the G4 to scale in Megahertz. If this occurs, hopefully the G5 will debut in the Pro models. This would be logical. I think if Apple releases the new iMac, they have to do better then just a new enclosure and new hard drive space. They should put a G4 in it to put the icing on the cake. This leaves room for the G5. Sum up: New iMac's with G4 in high end New Power Mac's with G5's *Not sure about speeds on any processors.
