Nintendo president Satoru Iwata was quoted as saying, "We are investigating. 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."
Nintendo obviously put a great deal of effort into play testing and providing evidence that their new controller was going to work for hardcore and casual gaming. The market has validated the idea 
with sold out Wii's all over the world. However, Nintendo misunderstood the excitement of the common gamer because wrist-straps are breaking throughout the Nintendo community
Similar to child safety seats, if you use it wrong it will be unsafe. This goes to show not all gamers, casual or hardcore, take the time to read the instructions and to operate the product as intended. Nintendo clearly intended the wrist-strap to be more than enough protection but this has been proven to be wrong.
Iwata say the problem is in the way the strap is being used - not the strap itself. Consumers need to be educated in its use? It may be easier to strengthen the wrist-strap because consumers want to game like maniacs, not read instructions or take classes in order to use their console.
The end result, broken TV sets, shattered controllers and bleeding gamers. Go figure...
