I think part of the reason is just about everyone knows how fanatic most Nintendo fans are, there is just no convincing them that Big-N might have screwed up.
I remember when they unveiled the 3DS for the first time, and being shocked that it still only had one thumb stick in this day and age. I was even more shocked to have not once heard anyone mention the lack of a second thumb stick when talking about the 3DS, and now this shit storm has started. I will never understand Nintendo logic.
No matter what you tell them, they will counter by saying that Nintendo has some kind of "magical creativity" that will overcome all the shortcomings of their product.
Might as well save your breathe.
