Sade, Zhane, Poussez and Wii: pronunciation instructions needed

You might remember those artists (coincidentally all females) whose names were provided with an explanation to pronounce correctly, i.e.:

Sade (pronounced Shar-day)
but in my head I pronounce it like Marquis de Sade

Poussez (say Poo-say!)
that's accurate!

Zhane (pronounced Jah-Ney)
Try Jah love! Billy Zane


Now the Wii wasn't provided with pronunciation instructions nor as to what does the W and the ii stands for?

If you've watched TV lately, you've seen commentators pronouncing Wii as Wheeeeeeeeeeeee!

How annoying!

If someone ask you to buy a Wii as a Holiday gift, you could reply ...

You want a Why-eye this year? It's sold out already! How about an Eye-pod instead?

and that someone to reply:

An I-Pod? Wheeeeeeeeeeee!

According to Wikipedia, it should be pronounced "we"
