Personally, I think this product will fail. It will fail. All the current competitors out there now, Xbox or Playstation. As well as that brand new portable products too: Gamestick, OUYA, iPads, phones or iPods. However it may thrive in the handheld consoles.
A major con of this model is that the screen is not protected like the other models. Therefore Nintendo will give you a super durable case, that will solve this issue. The 2DS will be released on October 12th 2013, and will be at the price of $126, which is nearly $50 difference from the 3DS.
I will not support this product, however, some people might like the fact that it has a new unique design, and that it is almost like a little iPad :D
