While the glasses-free 3-D functionality is certainly the chief draw of the device, Nintendo is being sure to make clear that this isn't just a Nintendo DS with a high-tech screen added to the mix. Under the hood, processing power and visual fidelity both get a boost while a built-in accelerometer & gyroscope create a wider range of gameplay opportunities. Of course, let's also not forget the addition of an analog control nub to complement the D-pad. The 3DS will be initially available in both blue and black colors. In addition to supporting the soon-to-be-released new line of 3D-enabled titles and Nintendo DS games, the 3DS will also feature built-in AR (Augmented Reality) gaming which require the use of cards that come packed in with the system. Right out of the box, the 3DS will also feature a built-in camera, a 3-D video player, a web browser, Mii support (you can create your own Miis, either from scratch or automatically, using a picture) and the same audio software featured on the DSi. Also confirmed is an improved Friend Code system; now, each code is hardware-specific and only needs to be registered once.
