Wii

The Wii is coming out soon, and there's a little detail that gets under my skin.

From the 'Pedia:

According to the Nintendo Style Guide: A Guide to the Proper Usage of Some of Nintendo's Products:

It is simply Wii, not Nintendo Wii. It is pronounced "we", indicating its all-inclusive nature. The name works best at the beginning of declarative statements. For clarity, it is best to avoid passive verbs and prepositions.

So, it's not the "Nintendo Wii". South Park's usage hasn't improved matters.
