According to Nintendo president Satoru Iwata, the DSi sold 300,000 units in its first two days on sale in the U.S. -- and another 300,000 units on its first two days in Europe.
Iwata's comments came as he discussed the company's intention to keep the price of both Wii and DSi the same -- he suggested that since they're on the lowest end of the hardware price spectrum, consumers are still likely to choose them.
"If products are similar, then people are going to look at which is cheaper," he said at his Foreign Correspondents' Club of Japan presentation, as reported by the Associated Press.
"We do not think our video game machines are that kind of product.... it is more effective to work on how to become No. 1 on the wish list," Iwata said.
During the presentation, Nintendo's Shigeru Miyamot also explained plans to have teachers at Japanese schools use the DS (and DSi) to give tests, as well as get maps, audio directions and coupons at museums and malls in the territory.
The same event saw Iwata conceding that the Wii's performance in Japan is "unhealthy" and suggested that the Japanese market might be already "tired" of its new technology, but said Nintendo has no plans to cut the Wii's price in Japan, either.
