Just as previously reported, the Nintendo Switch (previously known as the Nintendo NX) will rely on cartridges — or, more specifically, GameCards a la the Nintendo DS. Based on what was revealed in today’s first-look video, GameCards will slot into the main Switch Console, which can then connect to a television via the Switch Dock or directly into the controllers for mobile play.

Using GameCards is a good strategy for Nintendo’s hybrid device. Nintendo already uses flash memory for the DS, and games on cartridges are more portable than optical discs, are harder to pirate, and are harder to damage. (Especially in the hands of children, who remain the company’s core demographic.) They also eliminate the need for internal storage. Nintendo may be the only company relying on flash storage for gaming at the moment, but its unique case it makes a lot of sense.
