Apple has begun showing the teaser video for the upcoming Mac Pro in movie theaters across the nation. First shown at WWDC during the initial debut of the Mac Pro, the video shows the sleek black curves of the product from multiple angles. According to reports from several people who have seen the teaser, it ends with the line "Fall 2013," offering the first concrete hint of when the redesigned Mac Pro might launch. At WWDC, Apple gave a "later this year" release date. The new Mac Pro is a fraction of the size of the previous model and housed in a radically redesigned tower. It will come equipped with Intel Xeon E5 processors with up to 12 cores, dual workstation AMD FirePro GPUs, and new PCIe flash storage.
