Ok... lets try this.....
I judge how many nintendo fans remain by referencing the wiiU. Yes thats tru, and I won't fault you for jumping at that cause i didnt take the time to elaborate. As far as nintendo goes, you have their home console and their handheld console divisions. Lets start with handhelds.
Its easy looking at the 3DS and say but it sold 60M. But to do that and not mention that in sold only half as much as the 2DS would be to not see the full picture. The 2ds competed with eth PSP and still hadily won. The 3DS competed with the vita and also won. but the full picture is that there was in increasing presence in mobile gaming on smartphones that had taken up most of that handheld market and still does till this day. Proof is in the sales difference between the 2DS and the 3DS. And nintendo had always been dominant in the handheld space. If nintendo made a dedicated handheld gaming console today, no matter how good it is.... it will sell less than the 3DS, and we have smartphones to thank for that.
I snipped your post because you seriously don't know much about Nintendo. You think the 2DS sold more than the 3DS. You are struggling with the basics, like I said.
