Wii U
From Inkipedia, the Splatoon wiki
The Wii U is the 8th generation Nintendo console for which Splatoon will be released in May 2015.
Features
The Wii U system, similar to the DS and 3DS systems, comes with a second screen known as a GamePad. The GamePad comes with a touch screen, and some games can be played on the GamePad alone, just in case someone is occupying the TV. Much like the Wii can play GameCube games, the Wii U offers backwards compatibility with Wii games.
