Apple’s Worldwide Developer Conference kicks off tomorrow, and that can only mean one thing: several new announcements from Apple. Make sure you cancel any outstanding orders for Apple products, because there will almost certainly be news from the company after the keynote address is completed. Almost certain is a new Intel-based desktop (the Mac Pro), a pre-release version of Mac OS X 10.5 Leopard for developers, and likely additional software announcements. Various rumors include the release of new displays, new iPods, and an cell phone. I’d be surprised if the new iPod or cell phone makes the cut, but expect we’ll see some new accessories in addition to the Mac Pro.
