Update: Nintendo of Europe confirmed to Eurogamer that the New Nintendo 3DS will also be discontinued in Europe. Meanwhile, Nintendo of America told Polygon that this does not affect North American sales as the standard New 3DS was a limited offering to begin with.
So far, this listing has only appeared on the Japanese website, suggesting that the New 3DS with faceplates will still be available in the US and Europe. However, this leaves only the New 3DS XL, 2DS, and New 2DS XL as the only DS models still produced for Japan.
The "New" branded 3DS models were announced in October 2014 with two variants, an XL and standard model. Both of the New 3DS models featured enhanced 3D effects, a new second thumbstick (nub), and two additional shoulder buttons.
While all 3DS games could be played on the New 3DS models, certain titles were advertised as being for the "New" 3DS models due to their slightly faster CPU.
I personally love my standard New 3DS mainly because of the customizable faceplates that are available only for the smaller model. I just love it when I can personalize my consoles, and faceplates were a great way to bring a little flavor to the 3DS.
