A standard Nintendo DS card looks like this.
As seen in Nintendo’s E3 booth, a sample Nintendo 3DS cart looks like this. The design is pretty much like the Nintendo DS card, with the exception of a tab on the top right.
Nintendo 3DS appear to have modified packing too. The case seems to be slimmer than what Nintendo is using for DS games now.
