Wii name

[Grey Acumen]

NüWii

- Pronounced "New Wii" or "Newy"

This is the best name that Nintendo can use, in terms of still being easy to pronounce and giving a fairly whimsical feel, in terms of NOT using the stupid idea like "Wii2" or "Wii HD", and in terms of having the name represent, both through letters and visual appearance, what Nintendo's Philosophy is :

Wii = We, representing gamers together, the 2 i's look like people playing next to each other
N = Nintendo, representing how much closer this system will bring you to the console they made and being immersed in the games you play on it.
ü = You, representing the focus on the individual player's ability to interface with the game, using controls that can be simple or advanced depending on what best suits the individual player. Having the 2 dots above the u also acts to create the image of 2 players being connected by a line, which shows Nintendo's efforts of improving player's ability to connect online as well as irl.

 

And just cause RockOn's idea down below is really cool: N.ü.W.i.i. = Nintendo's Ultimate Wireless Interactive Interface
