I could be wrong, but I think there are a lot of people who don’t have a particularly good understanding of logical reasoning that make conclusions about the Wii’s user-base with limited (or no) evidence to support their claims.
Personally, the way I see it is there is a very tiny and very vocal minority of gamers who would never consider buying a Wii; and these gamers share a set of values that when combined make the Wii an abomination. From what I have seen these gamers tend to believe that a person would have to share none of these values in order to appreciate the Wii, and then make generalizations about the Wii’s user-base using this assumption.
The truth is that the vast majority of gamers would be willing to buy a Wii, and would appreciate it for what it is, even if they don’t own one and have no intention of buying one. Their reason for not buying one (yet or ever) could be something as simple as having another system (including something as old as the PS2) and all of their needs are fully satisfied by that system. At the same time, the vast majority of Wii owners share most of the same values (when it comes to gaming) as the most "Hardcore" Wii-Hating HD fanboy and would react to a new generation of consoles in a very similar fashion.
In other words, if Nintendo released a new system that was very similar to the Wii with a wide range of improvements and sold it at an affordable price people who owned a current generation system (including the Wii) would be interested in buying one. Whether Nintendo could match the success of the Wii depends heavily on when it is released, how much of an improvement it is, how affordable the console is, and the decisions Nintendo’s competition makes.
