I haven't really read that much into it, but I did watch the video from E3 where the people are showed pikmin and such in 3D. What I want to know is, does things actually appear like they are coming out of the screen? I know obvioulsy this wouldn't be picked up on a camera recording it.
Nothing pops out (its not a hologram), its more like looking out/through a window
I think most people know it's not holographic. They just mean that some things appear to be closer to your face than the screen does. Do to how the brain percieves the 3D effects it does appear to be popping out of the screen because your brain percieves it as closer than it really is. The 3DS adds a perception of depth, and apparently the popping off the screen too.
