According to Nintendo's sales data:
"Nintendo sold more than three million Wii consoles in the U.S. in December 2009, setting a regional record for the month and ending 9 months of declining sales, as a result of the price cut and software releases such as New Super Mario Bros. Wii.[82][83] As of the end of that month, the Wii is the best selling home video game console produced by Nintendo with sales of over 67 million units, surpassing that of the original Nintendo Entertainment System.[38]. As of March 31, according to Nintendo, the Wii has sold 70.93 units worldwide.[1], selling 20.53 million units within 2009-2010 fiscal year."

So apparently the Namco Bandai rep is smoking crack because Nintendo has outsold all the competitors combined with just the Wii, let alone their DS sales. Granted there's a current lull in sales but that's for any platform, especially one that's been out as long as Nintendo's, that and a lack of a "killer" game, and a market that's over-saturated by less than stellar titles, it's not rocket science to see why Nintendo's sales have been sluggish as of late.
No need to fear though or to claim that Nintendo's markets have collapsed. As for the Apple (& oranges) comparison, I seriously doubt that the iPad will outsell the Wii. Right now it's at 2 million, so it has another 68 million+ to go before it surpasses the Wii, then there's the DS:
"Units sold worldwide: 128.89 million, including DS Lite, DSi and DSi XL units (as of March 31, 2010"
Hmmm, yeah somehow I just don't see Apple coming anywhere CLOSE to that level.
To be perfectly honest, all things considered, Apple appeals to a relatively limited, target demographic with its iPad. They start out at around $600, so you're looking at mostly adults, particularly business oriented people, and perhaps some older adolescents, college students, but you won't see the average person with an iPad because it's cost prohibitive, and you're pretty much guaranteed never to see millions of kids running around with them because parents wouldn't trust their kids with such an expensive toy, let alone buying something so expensive for them in the first place. iPads will never be as ubiquitous as Wiis and DSes because they're somewhat cost-prohibitive. About the only way they would ever see the type of Nintendo sales figures is if they drastically reduce the price at some point to the $200 range, but even then they'd be hard pressed to rival the sales records set by Nintendo.
Different markets with different demographics, people that buy iPads generally don't do it for the games, it's for the Internet and e-mail functionalities, they view it primarily as a smaller, more convenient laptop without all the unnecessary overhead plagued by your average laptop, such as bloatware, anti-virus/anti-spyware programs, etc.
In other words, the Namco rep is full of it.
