I guess if I would've played Pokemon Black long enough instead of quitting after my Snivy got to level 10 I would've knew that XD.
If that is the case, the 3DS will most likely make some sort of video chatting app similar to ooVoo or Skype perhaps?
Video recording would be nice if not only you could record yourself, but also somehow attach the camera to the current game your playing and make
short videos with it..
