Sorry - not buying it
This has all the earmarks of a hoax... and a rather poorly researched one at that. Most telling is that all existing models of MacBook and MacBook Pro are shipping "within 24 hours" from Apple and BTO configurations are shipping in the normal 1-3 days. If Apple replaces products in their product line, you almost always see them lean out the channel in advance.
A change to the MagSafe power adapter is highly unlikely unless there's a major design change or a safety issue. Changing the cable end to aluminum just doesn't make sense.
As others have pointed out, the Mac Pro was just refreshed and the "specs" here are incorrect. This is obvious rubbish.
