Every other DS but the 3DS and its variants are 2D. Many games for the DS are 2-dimensional. A Nintendo 2DS would be a massive rip-off. Who'd even want to buy it? Most games today are 3D, such as Fallout 4, Star Wars Battlefront 2, and Halo 5. If anyone wants to play a 2D DS game, they should play one on their old DS.
Nintendo made the ds and it was good as it was small and portable. Mainly because you could fold it up. You cant do that anymore so why would anyone buy an oversized console which does not have the power capabilities to keep up with its competitors. Its just TOO big for my understanding
