There has been an increasing amount of analysis of what Nintendo should (or will) do from analysts recently, most of which didn’t anticipate the will; and most predicted it to be the last place console selling 10% to 20% as many units as it will eventually sell.
The Nintendo DS and Wii were systems that were envisioned and created based on the conditions within the market, and within Nintendo, from 2001 to 2005. There are a lot of similarities between these two systems because the same thought processes were being used to design these systems. The same could be said about the PSP and PS3, or of the Gameboy Advance and the Gamecube; and probably any 2 systems released by the same company would have many similarities.
Unfortunately, most analysts are terrible and have somehow gotten it into their head that the question they should be asking is "What does the Wii tell us Nintendo will do with the ‘Wii 2’?" when they should really be asking "What does the 3DS tell us about the ‘Wii 2’?"; and you could say a similar question that should be asked in a couple of days is "What does the PSP2 tell us about the PS4?".
At this point in time it is difficult to tell what the 3DS implies about the Wii 2, but I think it does demonstrate that Nintendo is willing to spend more on developing more advanced hardware; and also that third party publishers are going to bet far more heavily on Nintendo's new systems at lauch due to the success of their current generation systems. I could be wrong but if the 3DS is as popular as many of us expect it to be, it really won't matter what Nintendo produces third party publishers will support it by producing an order of magnituded more exclusive quality titles in well known franchises that are produced by established teams than they did with the Wii.
