Nintendo Japan has announced a new Switch bundle that comes without the dock, which makes it 5,000 yen cheaper (about $45) than the standard set. Alongside this, they also announced new Joy-Con colour variants neon green and neon pink as custom Joy-Con color options.
Think of it as a second unit bundle as it ships without the TV/charging dock, Joy-Con grip, power cord and HDMI cable thats usually included. Once Nintendo's online service for the Switch launches this fall it's cloud saves feature will make it easier to swap between 2 or more systems.
There's no indication if the second unit bundle will go on sale outside the Japanese region, but if Nintendo wants everyone in the house to have their own Switches, it does makes sense.
