No

I would doubt the capacity of games like Punch Out to boost hardware sales.

Saying this would imply that more traditionnal/core games is what made Wii success and that is not the case.

Wii success was based on marketing and selling new kind of party games.

The only game in that list that has capacity to boost sales is WSR and the question is whether people that did not purchase a Wii yet despite Wii sports, Mario Kart Wii and Wii Fit are going to be compelled to buy one because of WSR.

For WM+ I think it will be a success among current Wii owners but I don't feel it will expand the Wii market, technology is not why people have been purchasing the Wii.......

Basically everyone criticizes analysts for using old console paradigm to judge the Wii and you are doing exactly the same thing there...

Punch out IS going to do that. It's going to be a bridge game that will reach a wide audience. Just watch.

You're proceeding on the assumption that the situation as it is NOW is what the situation will ALWAYS be. While I dispute your assertion that "more traditionnal/core games (are not) what made Wii success" (sic), even if we assume for the sake of discussion that you are correct, offering MORE traditional/core games is precisely what will propel more hardware sales.

IF we go with what you're saying, the people who want Wii Fit, Wii Music, etc. already bought the system: appealling to the expanded audience will thus lead to diminishing returns.* By contrast, since you seem to believe that the console has overlooked the traditional gamer, then there are likely few of them on the system as it is: making games that target THEM will INCREASE console sales, because now they have a reason to buy in.

So, to go with how you framed the topic, either the Wii has already tapped into the traditional/core gamer, or Punch-Out!! only appeals to the expanded audience.† These are the only ways it will fail to increase hardware sales (judging from your post).

*This assumes, erroneously, that the expanded audience is one solid block, all of whom are seeking Wii-Fit-esque experiences from gaming.

†This assumes, erroneously, that the game is an either/or, rather than a bridge title.

Hard to compete with the SSBB, MKW and Wii Fit combo from this time last year.

Nintendo is obviously relying on WSR and other WM+ games to drive more interest over the summer, after the failure of Wii Music and Animal Crossing Wii.

The main thing that should worry people is that Nintendo would lead a holiday with two games without any content. Wii Music relies on user-generated content, and AC Wii is old content with new features. Hopefully Nintendo have learned their lesson.

A release schedule full of lesser hits with a back catalog of mega-hits can still drive record sales, though, as we have seen with DS. Problem being that a home console demands twice as many lesser hits, and third parties have stepped up half as much as they have on DS.

But overall, sales on the year are fine. This year, Wii sold 4.97M from the week ending Jan 9 to the week ending April 10. Last year, it sold 4.15M from the week ending Jan 11 to the week ending April 11. The difference is that last year, the Wii had a bigger sell-out in holiday 07, had next to nothing on the shelves early in Jan, then got new stock in place for huge software launches in March, April and May. This year, they followed a more traditional Dec-May decline without any big software until summer.
