What does WII stand for?

From wikipedia:

The console was known by the code name of "Revolution" until April 27, 2006, immediately prior to E3.The Nintendo Style Guide refers to the console as "simply Wii, not Nintendo Wii", making it the first home console Nintendo has marketed outside of Japan without the company name featured in its trademark. While "Wiis" is a commonly used pluralization of the console, Nintendo has stated that the official plural form is "Wii systems" or "Wii consoles." Nintendo's spelling of "Wii" with two lower-case "i" characters is meant to resemble two people standing side by side, representing players gathering together, as well as to represent the Wii Remote and Nunchuk. The company has given many reasons for this choice of name since the announcement; however, the best known is:
“Wii sounds like 'we', which emphasizes that the console is for everyone. Wii can easily be remembered by people around the world, no matter what language they speak. No confusion. No need to abbreviate. Just Wii.”

Despite Nintendo's justification for the name, some video game developers and members of the press reacted negatively towards the change. They preferred "Revolution" over "Wii" and Forbes expressed fear "that the name would convey a continued sense of 'kidiness' [sic] to the console." The BBC reported the day after the name was announced that "a long list of puerile jokes, based on the name," had appeared on the Internet. Nintendo of America's president Reggie Fils-Aime acknowledged the initial reaction and further explained the change:
“Revolution as a name is not ideal; it's long, and in some cultures, it's hard to pronounce. So we wanted something that was short, to the point, easy to pronounce, and distinctive. That's how 'Wii,' as a console name, was created.”

Nintendo of America's then-Vice President of Corporate Affairs Perrin Kaplan defended its choice of "Wii" over "Revolution" and responded to critics of the name by stating, "Live with it, sleep with it, eat with it, move along with it and hopefully they'll arrive at the same place."
