It seems that production has ran into problems with the Wiimote control for the Nintendo Wii. If this speculation is true, then this may be the reason Nintendo has not announced an official launch date.

According to GoNintend.com, this is what their source had to say:

“The factory has received a purchasing order for the Wii controller and a sample, but is still stuck in the testing phase. From the feedback of testers, currently the Wiimote and nunchuck still have a lot of small issues, such as buttons that aren’t sensitive, and that it’s hard to press two buttons together, (there’s even no response occasionally), and that the current sample is easily damaged – using the controller in normal situation will produce some noise, etc. Entering September, if the above hardware problems cannot be fixed, it will directly affect Wii’s selling strategy.

Also, the factory has not received the Wii console from Nintendo yet – currently, they are testing samples using a dedicated machine only for testing, which means that after an up-to-standard sample is produced, it still needs to be sent back to Japan to be tested by Nintendo for a second time. The Wii controller uses bluetooth technology for real-time data transfer, and infrared for “space location”, and the second phase of testing procedures maybe even tougher!”

Again, it’s possible this is nothing more than another Wii rumor. However, this could explain a lot of things, such as no launch date and delayed wii parties.
