when you look at file sizes for games that are popular, like CoD and GTA5...these files are HUGE. GTA5 is at least 60GB. Now, people think that just because they see a $30 64 GB SD Card, that it would be a no brainer for developers. But Nintendo would have to use their own form of the SD Card that allows certain features of their console. Flash memory is cheap, don't get me wrong. But it's the unknown that will get to 3rd party devs. Once we see more of the console, if this is what Nintendo is aiming for, then maybe we can speculate more.
3DS is doing great with a card format and I would love to see a triumphant return to card based gaming. True, load times would be faster but it all comes down to, what will be the sizes for these flash memory cards that the NX might use. By its release, AAA, photo realistic games will probably need 100GB of space.
