See? DS with better software overall and without competition was doing worse.
It had a different brand from GBA, it was marketed better than 3DS and it was sold at a smaller price. And was being outsold 2:1 by a 5 year old console.
The expectation of Nintendo and, generally, people were too high, it's doing fine from the beginning to now.
