The Register reports that the G5 has been cleared for volume production:
According to our mole, the G5 is tentatively being produced in three versions: 1.2GHz, 1.4GHz and 1.6GHz. We say 'tentatively' because there still appears to be some concern that there will be insufficient 1.6GHz parts for a commercial release. Says our source: "The chips that are testing at 1GHz are being set aside in case there are not enough 1.6GHz chips to release that machine."
