WiiU:Wii U Model Differences
Unlike many other consoles, the Wii U never received any major console revisions. The only models that exist are the two initial launch models, with the only difference being the internal storage space of the console. These two models were exclusively differentiated by their storage size. In terms of other hardware, they were completely identical.
WUP-001 - 8 GB Model
This model only came in the white color, and was known as the Basic Set in North America, and as the Basic Pack elsewhere in the world. Unlike the 32 GB model, there were never any other official colors for this model anywhere in the world.
WUP-101 - 32 GB Model
This model initially only came in black, and was knows as the Deluxe Set in North America and the Premium Pack in the rest of the world. About seven months after the console's initial release, an official white Premium Pack was released in Japan exclusively. This was the only way to purchase a brand new 32 GB white console. However, in North America, Nintendo sold refurbished white models with the storage upgraded to 32 GB, along with the model code WUP-101.
