Nintendo has announced that worldwide, the Club Nintendo loyalty program, which allowed members to earn "coins" by buying Nintendo products and filling out surveys and use said coins to buy games and trinkets, will be deprecated this year.
Nintendo has said that a new loyalty program will be set up, but did not go into detail.
EDIT: For clarification, this means Club Nintendo is ending. Coins/Stars will not transfer to the new system, so spend them. I can't speak for NCL or NOE, but NOA will be adding more items next month to encourage people to spend all of their coins.
