no not right now l don't see anything about wii sports club on pretendo website but i have a theory of why is's not developed yet disclaimer- l don't know when pretendo plan if somebody who knows can clarify that would be great

l don't think wii sports club is a high priority game to develop i'll use splatoon as an example l think splatoon is a high priority because half of it's functionality is broken and it's a popular game wii sports club is probably medium priority you can use the application

wii sports club multplayer and leaderboard isn's as important as splatoon online multplayer and the shops and splatoon is more popular but it's just a theory a game theory
