A new trademark for Legend of Zelda: Breath of the Wild adds even more credence that the Nintendo NX's games are on cartridges instead of discs.
Some time ago we reported that the Nintendo NX might use game cartridges instead of discs, almost akin to a 3DS handheld. This info was gleaned from a patent, but patents don't always reflect final products. Thanks to the clever sleuthing of NeoGAF user Aetheerios, Nintendo might have inadvertently confirmed the patent information.
A new trademark for Zelda Breath of the Wild, which is releasing simultaneously on the NX and the Wii U, clearly lists "video game cartridges" as a game distribution medium. Now this is actually pretty interesting, given how Nintendo's classified its games thus far. For reference, Nintendo only marks its 3DS games as cartridges games, whereas Wii U-only games are only listed as disc-based. Since Zelda Breath of the Wild is launching on both the NX and Wii U, it lists both cartridges and discs: disc for Wii U, leaving cartridges for the NX.
