I dont think Nintendo Network is shutting down anytime soon lol The E-Shops are still connected to it and you can still link your NNID to buy games through the Nintendo Online Website and get them automatically installed on your 3ds / Wii u Also Nintendo gave an official interview in 2014 stating that they wont shut down NNID as early like they did with WFC on ds and Wii they said they will keep it running as long as possible even if nobody uses it Their plan was all the way till the 2030s They probably got sick of Miiverse because moderation was expensive and they got annoyed by the exploits and hackers lol
