Nintendo really is moving on from the Wii and Nintendo DS eras. In addition to deactivating online capabilities for last generation's hardware, the company will also soon stop awarding bonus Club Nintendo coins in exchange for registered new copies of games from those libraries. Time is running out if you're hording any codes for a rainy day. There's a storm coming!
Starting on April 7, 2014, any newly registered Nintendo DS or Wii games (both retail and digital copies) will continue to receive product registration surveys, but no longer be eligible for 10-coin post-play surveys. In addition, starting on April 7, the deadline to complete newly earned post-play surveys for all games will be 30 days after they are issued.
This was bound to happen as the Wii and DS move further into history. Once upon a time the company awarded digital goodies such as wallpapers and screensavers when registering GameCube games and, later, Club Nintendo coins; of course, those privileges are long gone. Register your codes while they're still worth their current maximum value. The deadline for Platinum member status is quickly approaching.
