Gamasutra noted that
Nintendo President Satoru Iwata, in a briefing, affirmed to continue supporting the DS gameboy system following the launch of the 3DS, expected to be released in Feb. 2011 in Japan.
<blockquote> (Iwata) explained, “We have experienced several transitions from one platform to a new generation in the past, but the speed at which such transitions were made greatly varied in different markets.” The executive said that he thinks Japan is the quickest to shift to new platforms, as is the UK, while Germany is slower in such transitions.
He added, “In the U.S., so many people respond to new platforms quickly, but as for the entire video game market there, it appears to move rather slowly because there are also so many people who respond to new offers very slowly.”
The Nintendo DS, launched in late 2004, has sold over 135 million units worldwide, making it a difficult platform to immediately ignore, despite its age. “…Naturally, it is desirable for us to be able to make some new offers to those who already own Nintendo DS,” Iwata said.
