Famitsu asked Nintendo about several issues regarding NS. Here is the summary of the article. As my Japanese is crappy, please tell me if there are any mistakes.

- NS is not the successor of Wii U
- NS is not backward compatible with Wii U and 3DS
- NS will be packaged with Joy-Con(L) and Joy-Con(R)
- The packaging of other accessories will be announced separately for different regions before launch
- Cartridge is called "Game Card" internally
- Specifications of cartridge will be announced before launch
- Battery life will be announced later. The development team aims at allowing players to play NS conveniently at places without electricity connection.
- At this moment, no information on compatibility of smartphone apps can be provided
