WWDC kicks off in five days, and it looks like we at least know that we can expect a slew of new Apple Mac hardware and accessories. We're talking new MacBook Pro, iMac, MacBook Air, and even a very long-awaited update to the Mac Pro line. In addition, a new Airport Express seems to be in the cards, along with a new USB SuperDrive and USB Ethernet adapter that we are guessing will support USB 3.0. You can see the leaked part list above--here's hoping that those MacBook Pros are sporting Retina displays!
