There has been a lot of speculation about the 3DS, but we still don't even know how the 3D will be implemented. Some people have pointed to a DSi game as an example of how Nintendo will choose to implement the 3D effect: http://www.youtube.com/watch?v=p3lDoVwEmts Others think that it will use a special type of screen to provide an effect similar to that you see when you watch 3d movies like Avatar. But, maybe nintendo will take a completely different route altogether! Perhaps they have found some way to utilize the 2 screens together to create a 3d effect? Or something that no one has even thought of yet?
