Wii U Premium Set to be released in white
As confirmed by Kotaku, the new version of the Wii U Premium Set will come in white. The Premium Set will be priced the same as the other versions/colours of the sets, $315.
This means, though, that you will have to be a bit more cautious when buying the systems. The reason for this is simple: Before the new version, you could tell the difference between the Basic and Premium by the color of the consoles (before the Premium Set was available in black only while the Basic Set was in white only).
The console, holding a 32 GB drive, will be available on July 13 in Japan. There is no official release date set for the United States as of now, but details are expected to be announced at the upcoming E3 event.
