Apple will unveil its Power Mac G5 replacement at itw Worldwide Developers Conference next month:
While specifics were not disclosed, the new computer's case is said to be substantially different enough to make the distinction between the new Intel Core 2 Duo-powered system and its PowerPC predecessor easy to spot. While Apple has traditionally matched new processors with new enclosures—as it did with the PowerBook G4, iMac G4, and Power Mac G5—the company surprised some observers when it debuted the Core Duo-equipped MacBook Pro in January clad in the aluminum skin of the last PowerBook G4.
Configurations of the new Mac are said to be similar to those of the most recent Power Mac G5, including a single dual-core processor in the low- and mid-range systems, and a dual dual-core (quad core) system at the top end.
The MacBook Pro will also get a new enclosure when the system adopts Intel's Core 2 Duo processors. More details at ThinkSecret.
