Nothing has been confirmed by Nintendo in regard to exact release date, price or launch library, but GameStop has begun it’s reserve program for the 3DS console and a few games.
A $50 deposit is required to hold your console that is set to release sometime next year. No word on colors or anything like that, but Nintendo historically starts with one color for their handheld launches.
There are a few games that can be reserved, as well. With a $5 deposit, you can guarantee yourself a copy of Super Monkey Ball, Sims 3 or Cartoon Network’s Super Toon Rumble. Hopefully the launch lineup will gain more titles soon.
