If you know for sure you're going to want a Nintendo 3DS whenever the system is released (sometime around March) and at whatever price, you can now pre-order the handheld from GameStop. You'll have to pre-order it in 3D, though -- by which we mean go to an actual store, rather than shopping online. According to Engadget, different stores are asking for either $25 or $50 deposits. At the moment, searching for "3DS" on GameStop.com redirects to a page where you can sign up for updates about the system.
We suspect we'll find out the final price, along with other details like launch colors and software lineup, at Nintendo's January 19 event in New York City. This is also likely when we'll see pre-orders begin at other retailers.
