My opinion is that 3D display will be a part of Nintendo's next handheld, but not the main focus or there will be another feature that sets it apart from the competition. Like the DS had two screens, but what made it special was that the bottom one was a touchscreen. I believe that Nintendo will use the 3D display to make it's competitors believe that this will be next step, while they will also have something else to stay ahead.
Otherwise I have no idea why they announced this through a message sent via their investor's information page which anyone with an Internet connection can view, instead of announcing it at E3.
