By now many of you have probably heard of (and maybe seen on YouTube) the various Wii incidents that new owners of the Nintendo console have experienced. Besides the fact that some people are actually complaining of "Wii ache" or soreness from swinging around the remote, the bigger problem is that the remote itself has a hard time staying in a person's hand, especially if that hand becomes extra sweaty during an exciting Wii gaming session.

In several cases, the Wii remote strap that holds the controller to the wrist has torn completely free sending the remote flying like a missile into walls, floors, and worse yet big screen televisions (sometimes cracking the screen as a result).

Today, according to an AP report, Nintendo President Satoru Iwata admitted that there may be a problem with the controller's strap.

"We are investigating," he said at the Foreign Correspondents Club in Tokyo. "Some people are getting a lot more excited than we'd expected. We need to better communicate to people how to deal with Wii as a new form of entertainment."

Indeed, some people have been playing games like Wii Sports by swinging the remote with all their might, and although that's one way of playing, it's certainly not necessary to be successful at the game.

At this point it's not clear what Nintendo plans to do about the Wii strap, other than to make sure that consumers are fully aware of the dangers of it breaking from excessive swinging force. Nintendo has already warned players that they need to wear the strap at all times, and that they should try to maintain a tight grip on the remote when playing a more physical Wii title.

Wii sales thus far have been very encouraging for Nintendo, so much so that the company may revise its sales target upwards, Iwata said. The console has already sold more than 600,000 units in the Americas and close to 400,000 in Japan. Nintendo has repeatedly said that its goal is to sell 4 million worldwide by the end of the year and 6 million by the end of next March. If the rest of the holiday shopping season goes as Nintendo would like it to, the company may raise that 6 million target.

"I'm not ruling that out entirely, but it's premature to say it now," said Iwata.
