I don't think I will buy it until someone crack it.
As far as I know, NDSi cannot use R4 card, meaning you have to buy orignial game.
But there is hope because I think NDSi has a slot.
Some experts told me if there is a slot, there is a way to invent something like R4 card.
It just the matter of time.
As for the camera, I think it's not an actual camera since the pixel is very low....
