The perennial problem with Nintendo is that they are a stodgy, overly-conservative company. They were late to the party with optical media, 3D, networking (they still don't have a great story), selling downloadable software through an online store, and they still haven't tried to release a proper grown-up console in the living room. Handhelds are the only thing they've done right since the Nintendo 64.
The 2DS is a recent example of their continued conservatism -- Its a cost-reduced version of the 3Ds lacking 3D and designed for lower cost of manufacture (simpler body, no folding). One of the cost-cutting measures takes the form of there being a single large LCD panel inside, rather than two separate displays. The plastic bezel blocks the unused portion of the screen to mimic the traditional 3DS screen format. The entire panel is touch-sensitive too, but only works on the "lower" screen like the 3DS.
It was launched alongside the latest Pokemon games, and pitched as a cost-sensitive option for parents with pokemon-obsessed youngsters. Aside from the unusual form-factor, I think they mostly achieved in that promise -- sales of the 2DS have been good.
But, as usual, their overly-conservative approach has led them to miss a golden opportunity -- For literally no additional manufacturing costs, and little additional development costs, they could have simply exposed the entire LCD panel, and enabled developers to create titles specifically for that screen format. And by doing so, they could also have opened up the door for enhancing certain features on the 2DS -- for example, not having arbitrary screen-size limitations could have enabled virtual-console titles to occupy a larger portion of the screen (one not limited by having to mimic the limitations of the 3DS). Since they intended all along to launch it alongside Pokemon, they should have packed in a touch-enabled Pokedex application (either a pack-in cart, or build into the units firmware even). The screen format would have been suitable for an eReader application, and certain kinds of educational apps too, giving them even more ammunition to convince parents to part with their $130.
So why didn't they do this if it wasn't going to cost them anything, essentially? Because someone in a Nintendo boardroom was paralyzed with fear over thinking that consumers were too stupid to tell the difference between 3DS software and 2DS software sitting on a shelf at WallMart. Or scared shitless that they might "dilute their brand" -- No, they can release a hundred variations of every handheld since the original gameboy, but this one utilizing the entire screen was simply a bridge too far. And the kicker, well, that's the part where they've got their heads looking back over their shoulders at history to guide them so much so that they can't see the present -- a present where those quaint little online stores entirely obviate the problems of customer confusion, brand dilution, and competition for shelf-space with other software that they're so completely frightened of.
Nintendo gets given a pass for their past 10 years in the living room, but their apparent direction and past performance IMO is far more troubling than the one monumental fuckup that Microsoft perpetrated with the pre-launch XBox One DRM scandal. Microsoft's issue blew up, Nintendo's issue is fizzling out.
... So no, I don't see Nintendo launching anything like what you described in the near future, and if to my shock they did, I would be doubly amazed if they didn't ruin it by steadfastly hanging on to their own obsolete notions.
