3DS is selling better than ever, with Nintendo president Satoru Iwata telling the Nikkei newspaper (via Andriasang) the system is about to tip the scales at 3 million units sold in Japan — two weeks quicker than the DS reached the same milestone.

The news comes a week after Nintendo confirmed 3DS beat the DS's first-year sales in just eight months.

Iwata also spoke briefly of Mario Kart 7's sales in Japan, where the racer sold a staggering 420,000 units in its first week, about double the first week sales of Mario Kart DS.
