2DS is being launched to make sure Pokemon reaches as wide an audience as possible, by lowering the entry barrier to 3DS software. The only way Nintendo can do that is by cutting the price of the hardware, and the hardware price can't come down without removing the most expensive component.
People often believe that Nintendo use their software to serve their hardware, when the opposite is true, particularly in this instance. The 2DS has been created to serve the goal of making Pokemon as successful as possible. With just the XL and the 3DS on the market, Pokemon wouldn't reach the broadest possible audience, because hardware pricing leaves the entry barrier too high. Combine that with ongoing concerns about 3D for children, and the less robust clamshell design, and Nintendo clearly had issues to adjust before Pokemon X&Y can strike a chord with a truly mass-market audience.
2DS answers those issues. It's launching on the same day as Pokemon not because it needs Pokemon to succeed, but because Pokemon needed a lower priced, kid-friendly 3DS to reach the biggest possible audience this Christmas.
