While the new Nintendo Switch (NX) going to release in 2017, Nintendo still have to do something with the current home console of the company the Wii U.
The console currently available in Premium Set and in bundle set like with the Mario Kart 8 or with the Splatoon version.
At the moment most of the customers choose between the Wii U Splatoon set and the Premium Set but Nintendo today announced they will end soon the production of both of them. The Splatoon version at the moment runs for 39 960 Yen and the normal Premium Set for 32 400 Yen (both of them with tax).
Nintendo at the moment announced the production end only for the Japan market. If you want one of these buy it soon because Nintendo maybe going to end the production from one month to another.
