Yeah, the O'Hara's figure is from 2010, so I wouldn't be surprised if their domestic sales had increased as a rising tide lifts all boats, or so Bertie told us when he said the boom just got boomer.
But, I would be serious surprised if their domestic sales had grown that much. But maybe. Do you have any source for the figure?
I think the other micros are "looking" at exporting, but not actually doing anything about it. i.e. maybe some day.
