"Certainly, we've designed Nintendo Switch in a way that it can be used by consumers in the way that best suits them. I think we may see that people who have bought a Nintendo home console in the past traditionally, they may treat Switch like a home console and buy it and use it for a long period of time."
"Whereas people who have been traditionally Nintendo handheld gamers, they may buy Nintendo Switch and then for example, if a new version were to come out later, then maybe they would decide to upgrade to that. Or, for example, because you can take the Joy-Con off the system, then I guess that leaves open the possibility of something else that might get attached. There's obviously a lot of different developments that we could look at from that perspective as well."
"We're hoping that Nintendo Switch will be a system that will be the constant in your gaming life," adds Koizumi. "Whereas previously, you would play certain things on your home system and certain things on your handheld. Our hope is that Nintendo Switch can be the system that bridges both of those and becomes the constant system that you're always using."
Koizumi envisions scenarios in which, say, you wake up in the morning and maybe find some time to play a game on your TV while eating breakfast. Then you bring Switch with you on your morning commute to work or to school. "And then you're coming back home on your commute and maybe you're sitting in the bath enjoying a game," he says. He believes that if Switch can achieve this, then it might hasten the demise of the split between a "home console" versus a "handheld."
"Because you can remove the controllers from the system, it opens up a lot of possibilities for expansion of what you're able to do with the controllers or what you're able to connect to the system," says Koizumi. "I'm sure a lot of people have lots of different ideas about what might potentially get connected to the system, and perhaps suddenly one day, we'll just pop up and say, 'Hey, now there's this', though I can't give you any examples right now.'"
"Certainly, graphic quality falls somewhere within our priority, but our feeling is that Nintendo Switch is a system that really has the best balance of being able to create fun and new ways to play, but doing so with the graphic quality that's still good enough while also being one that's easy to develop for."

In this interview is he hinting that we will have different types of hardware similar (maybe something similar like 3DS family), and that Switch "Pocket" just for handheld gaming is almost certain. All that basically means there will not be successor to DS/3DS family, instead it will handheld that will be part of Switch family, and that makes most sense, because all devices will be playing same games and Nintendo will developing games just for one platform instead dividing resources to two different platforms.
But not only that, they also hint that we will have addons that can be connected on Switch or that Switch can be connected, AR/VR for instance.
