Satoru Iwata has revealed why Wii sales have been flagging recently. Apparently it’s all because there haven't been enough decent games. Well, gosh...

In the Nintendo President's own words the Big N has been “...unable to show a new game to become the next big thing”. And the brutal honesty continues, as the Iwata tells delegates at a recent Japanese press conference:

“In the game market, once you’ve lost the momentum, it takes time to recover”

To make matters worse it seems that the recent worldwide Wii price cut hasn’t done very much to reverse the downward trend either:

“With the price drop sales returned to a certain level, but they just did not reach the levels of last year around this time. We decided that it would be difficult to sell enough to recover from the poor performance of the first half of the year.”

So that’s quite a confession, especially coming from the boss of the company. Although we guess Mr. Iwata has to explain at least some of the reasons behind Nintendo’s recently posted financials – profits for the first half of 2009 have fallen by 59% compared to the same period last year.

However things should perk-up for the second half of the year – Wii Fit Plus (out today) is already doing good business, tripling hardware sales in the week of its Japanese release. New Super Mario Bros. Wii might shift a fair few copies too, as should Super Mario Galaxy 2 and the new Metroid game in 2010. But are any of those the “next big thing”?
