Arduino Micro Debut in the US

What's this note: "Arduino Micro in available in preview until December 1, 2012 at the following distributors..." on the Micro's buy page?

Does it mean it will not be available anymore, and for an undetermined time after 1th of December?
I'm asking because we're about to kick-start a project that would likely be based on the Micro, but we cannot wait for months for its availability when we're done and ready for production...
