Alright then, so we seem to agree that users of these games like Wii Sports and Wii Fit are giving up after "a short period of time." 

Do you think that this leaves them with a favorable opinion of gaming?

What do people do when they give up on a particular game? That's right, they buy another game ... This is why (despite all the claims that Wii systems are collecting dust) the Wii is able to maintain a similar per-system software sales rate to the PS3 and XBox 360

@Words Of Wisdom: give up already you know you are wrong

Logically speaking however, if you look at the attach rates presented as gospel then consider your own game collection.  If you're like me and you own 10+ Wii games then that means that at least 2 people out there who only own Wii Sports.  I know at least 5 people with collections like myself.  This is why I dislike averages.  I'd much rather be looking at distributions.  How many Wii owners own 1 game, 2 games, etc?  Just going from averages there's no solid conclusion you can actually draw.

Proving that Nintendo is not just selling to new customers but also transforming them into repeat customers would require far stronger proof.  The widespread beliefs and views that games like Wii Sports and Wii Fit get played briefly before getting shoved into closet to collect dust does little to assist one's hunt for that proof.  In fact, those rumors coupled with the knowledge that I alone am skewing the attach ratios should be a fairly good indication that Nintendo is failing to create repeat customers on some level.

The research Gosen sites is from his own company and he does not give out any details. Without knowing the question or the possible responses, you can shade the discussion of results a lot of ways.

In 2004, Gosen also paralleled Nintendo president Satoru Iwata's recent comments, saying that publishers have been focusing too much on a single demographic of consumers - and not appealing to women and other audiences. He feels Nintendo has the experience and know-how to best handle these console transitions.

What this may indicate is that Gosen appears to say whatever those who sign his paychecks want him to say. He has had a lot of positions. For the last four years, he has been at Digital Bridges/I-Play. He has also served in senior management positions at British Sky Broadcasting, Mercury One-to-One, Pepsico and Coca-Cola & Schweppes Beverages. http://www.gamasutra.com/php-bin/news_index.php?story=17944

It appears he may be Microsoft's casual gaming man and he is trying to downplay his chief rival and undisputed market leader. So you talk trash -- the Microsoft way -- about the rival's top product.

What about the people who own 20+ XBox 360 games, there must be tons of people who only own one XBox 360 game ... The thing you don't seem to be getting is there is NOTHING that has been demonstrated that shows that the owners of the Wii are reacting to the market in any (dramatic) way different than PS3 or XBox 360 owners.

I must say that I'm really getting sick of this double standard that trolls seem to use against the Wii ...

According to these trolls, there is no market for core games on the Wii because everyone who owns a Wii is a casual gamer, yet every last one of them owns a Wii that is collecting dust in spite of the fact that these handful of core gamers have to be buying hundreds of games to compensate for the fact that these casual gamers are not buying games.

I love smack talking, Nintendo is the only one who doesn't do it and it drives the competition mad, lol!

I have not mentioned the 360 or PS3 in my posts above.

Is there a reason you decided to A)  Ignore my point,  B)  Bring the PS360 into this discussion, and C)  Call me a troll?

I believe that all three of those were unnecessary and the last one is quite insulting.

Nintendo is a proud company they don’t go down to that level

Is it really that surprising though? In the last 10 weeks some ~3.8 million people have purchased a Wii and the vast majority of them probably only own one game or are at least weighing the average down considerably. 

That's not to say new purchasers shouldn't be considered, it just isn't surprising to me that dedicated gamers are offsetting this newer group.

If you want to break it down at a coverage rate of 2 to 1 there would be about 1.9 million folks in that 10+ range you were referring to.  That accounts for about 6% of the Wii user base and honestly sounds about right to me.  After all those with no games and those with lots of games are the extremes, those with fewer games are obviously going to outnumber those with a lot since everyone must enter from the bottom level and there is a constant influx of new purchasers.

The proof in whether or not nintendo is bringing in repeat customers will be in the attach ratio data over time.  If the massive influx of new gamers are not repeat customers the attach ratio will go down. It's pretty much that simple.
