CNET reports that Apple recently included photos of a yet-to-be released Power Mac G5 in a service manual, suggesting the the company will soon introduce updated models. The photos show a single heat sink covering dual G5 processors and a new vertical memory configuration. CNET also notes that the new machines could be released “sooner rather than later” because wait times for the G5s have recently climbed to seven to 10 business days on the online Apple store.
