With Microsoft's Windows Vista released and being integrated into today's PCs at full speed, Apple can't be expected to just sit around and watch Windows get PC sales. We could possibly see a refresh of everything from the Mac Mini to the Xserve. Apple workers have confirmed one important thing though- a black iMac. The 20" and 24" versions will have a nice black paintjob, similar to the black Macbook and the black iPod Nano. Mac Pro's could get upgraded to eight-core models, and we may see a low-priced 15" Macbook. There are also rumors of new iCinema displays with HDMI ports that support HDCP content.
