Nintendo sold roughly 400,000 of its new 3DS handheld in Japan this weekend, according to estimates. Nikkei (via Andriasang) reports that the company shipped over 400,000 units to retailers for its February 26 launch, and most are already sold out of their initial shipments.
Nintendo plans to sell 1.5 million in Japan by the end of the month, and is already sending out its second shipments. It will also ship 4 million units worldwide by March 31, which means plenty to go around in Europe and North America when they hit on March 25 and 27, respectively.
By comparison, the Nintendo DSi sold about 500,000 units in its first month in Japan. Of course, the DSi was more of a minor revision than a major upgrade, so the slower sales make sense.
