AI reports the eMac G5 was put on hold and the current G4 is back in production. The main culprit for the delay is the shortage of the G5 chips. The emac G5 was going to use the 1.6 Ghz G5 but, they want the chips to go to the iMac G5. Also, the G5 eMac was going to have a significant component reorganization. Apple is planning to release the new eMac revision in early 2005. Which sounds to me it would be MWSF.
