I wasn't told it was the last one by a salesman. I decided which bike I wanted and ordered it, and saw the available stock on the giant site go from 1 to 0, and crossed my fingers that one was mine. While there may have been some in shops somewhere, it was not in giant's interest to show zero stock if they had better information.
And I am pretty sure that year there would have been no avail 2 in size small by August.
