As it's such an abstract name/word, the advertising for it can be really good!
People will not automatically think urine when they see it as they'll just see the letters W,I and I.
For example, you have an advert (visually, not TV), it's plain white with the logo "Wii" on it and a date underneath. How can you relate this to urine, that won't be the thing cropping up on people's minds as they won't see the pronunciation... they'll be thinking what it could be, this kind of advertising could work for Nintendo.
Another, plain black poster with the blue light central with Wii and date underneath.
Simplistic advertising is the way to go for Nintendo in places like magazines and posters, when on TV then they should go along the route of the DS, to show the physical implications of the controller.
If you look on the advertisement ideas thread

there are a couple decent ideas on there (YenRug's is very clever and Catterick's is great - it would be Nintendo taking the mick out of themselves in a similar manner to how budweiser do now in regards to football/soccer)
Wii really is a great name, universal, easy to pronounce, very simple and minimilistic and they logo can be quite catchy!
Only in the English speaking countries (not all of them) can it be taken out of context and thats by fanboys really (people who "want" to find something bad in the name), the average Joe on the street won't think urine!
Look at Virgin, a huge corporate brand and people don't think about young ladies who have not yet been "spoiled", when talking about it or watching their adverts!
