Looks like you can move most DSiware to 3DS Linky here: here1 Linky here: here2 You won't have to rebuy all those games like Shantea, etc again. It is going to be like palpark, YOU PERMENANTLY MOVE them from the DSi to the 3DS. Don't expect to move it back. For those that do trade ins to upgrade, this might be an worth while option. But you have to transfer first before you trade in your old DSi.
