If you're installing games or parts of them to the internal flash (assuming Nintendo doesn't include a hard drive) they aren't going to load substantially faster off a flash "cartridge" for anyone to give a shit, especially when the third-parties are already designing their game to stream with the optical drives of the Xbone and PS4 in mind. This isn't like the double speed CD-ROM of the PS1* vs. N64 here. Plus the other two consoles have hard drives to cache on. (And especially if the textures are one-fourth the size...I mean, a lot of Wii games didn't seem like they had any loading times vs. 360 comparatively.)
Remember when just installing to a HD broke Halo 3 or whatever it was because of the stream timings? And increased the load times in a bunch of other games.
It looks like a Flash ROM of 32GB costs around $2 per chip, that's surely more expensive than a disc.

And both are more expensive than a code on a piece of paper in the box.

One of the cool things about cartridges back in the day is you could add additional hardware to them, such as the Super FX chip, to boost the console's performance without the need for external accessories or entire console upgrades.

(I don't know if such a thing would still be possible, but it was cool back then).
Nintendo could put new technology in the cartridges, the console would never be underpowered and you wouldn't need to buy an "upgrade" or new console, just a new cartridge and already get next gen, next level experience. :o
