The wording is interesting but the DS sold 1.36m in the americas back in dec of 2004. So I'm guessing we are looking at a larger number than that
endo confirmed this morning that first-day 3DS sales in the U.S. were the highest of any Nintendo hand-held system in its history. The company, however, would not provide an exact number today. It will reveal first-week U.S. sales early next month.
"More details about U.S. sales numbers will be made public on April 14, when first-week U.S. sales figures will be tallied by the independent NPD Group," a representative said. "Nintendo worked hard to get as much product as possible to retailers on day one to meet demand, and we will continue with these efforts moving forward."
