Though we are hesitant to speculate on announcement/ship dates when we’ve been repeatedly told by sources about delays and changes in direction for the 2010 Mac Pro roadmap — on top of the usual reasons to avoid staking our reputation on the most changeable element of any product release — we do believe that this revision is imminent and that we are looking at a timetable of weeks, not months.

A number of other improvements have been reported by sources in various stages of the prototyping process, including beefed up power supplies allowing for more wattage to CPUs and PCI Express slots (the 300W limit for all PCIe slots in current models would barely be enough for a single NVIDIA 400-series GPU), an improved built-in speaker, and any number of changes to the enclosure….but we’re not prepared to get into further detail on those elements at this time. Please feel free to send us any specific questions (or comments, corrections, etc) you have which were not answered by this article by your preferred medium — email (rumors@macosrumors.com), Twitter (@MacOSRumors), AIM (MacOSRumors), or the comments form below — and we’ll do our best to answer them as soon as possible.
