I would be surprised if Gamestop even has any information on the NX's details and formats at this point. They're simply a retailer, its not as if they do much beyond put things on their shelves.
I do think we should hope that it does indeed being something like flashdrives for physical media, sorta ala the chips that you see on the 3DS games. Flashdrives are actually quite cheap at this point, even in very large GB sizes.
but more importantly a flashdrive/chip sort of media would most likely mean a combined library for some sort of NX home console or handheld (or even that the system itself was a combination of both with some sort of controller that doubled as a handheld)
