The new Media 100 system, 844/x is a windows only system. They went with windows because when they started to develop it, "macs didn't have enough PCI slots and the PCI bus speed is well behind that of the Compaq workstation chosen for the host". 844/x has 3 PCI cards. They will continue with the Apple and windows versions of the NLE. Though it could be a timely move for Media 100 as FCP is taking chunks out of their existing market. It is a worrying sign though, as another company drifts off to windows.
