Nintendo DS to Add Music and Camera?

Nintendo’s DS handheld gaming system has proven wildly popular, consistently outselling competition like the Sony PlayStation Portable (PSP) and reaching out new markets with titles that appeal to kids as well as adult casual gamers and even seniors. And while the system is projected to sell as many as 28 million units this year, that would still be a decline from the 30 million units Nintendo sold during its previous fiscal year. And the basic system has been on the market almost four years, although Nintendo has been doling out new variants and colors.
