I didnt say it would.
He said, "anyone that thinks that the 3DS sold 70+ millions "in spite" of its 3D has no idea what he's talking about."
To me that implies that 3D was a major selling point of 3DS and sales would have been much lower without it hence why i asked him that question.
It implies that 3D had nothing to do with the problems 3DS faced in its first year, and once that it had the software to sell it and an adequate price point is started selling great. If the hardware is undesirable, no ammount of good software and/or offers could help with that, see Wii U as an example.
Looking at last week's Media Create numbers, for all its new models and cheaper price, the New 2DS isn't exactly destroying the 3DS sku in sales in Japan.
