Well... The DS sales included DSi and the DSi had exclusive games so... Yea!
Plus its just a slight upgrade, its not a brand new next gen Nintendo handheld so theres that... Plus they are combining vita + vita TV but the vita has exclusives so yea, it doesn't make any sense not to if they did it for both the Vita and the DS
