Well, this is unexpected. Nintendo is obviously denying it, but I wonder if this is the first step in them shifting away from 3D entirely. Wouldn't shock me if their next gen handheld abandoned the format.
At least to my eyes, 3D has mostly been a gimmick with no gameplay benefit. If the next iteration of the handheld could get it right (still no glasses, much larger sweetspot) I'd still have interest in the tech. But generally I play my 3DS games in 3D for all of fifteen minutes to "ooh" and "ahhh" and then go back to the much easier on the eyes (and battery) 2D mode.
In that sense, 90% of the 3DS experience for a lot of players who ignore the feature is retained in this device, for a decent chunk of change less. So if you don't give a toss about 3D this isn't a bad device.
But then what's up with Nintendo and wretched hardware design these days? I miss the days of simple elegance that came from products like the GBA SP, GBA Micro, DS lite, and DSi. All current iterations of the 3DS/2DS lines look cheap and even ridiculous. It makes Nintendo's hardware stand out, sure, but for the wrong reasons.
