If you purchased a Wii U season pass for DLC related to Batman: Arkham Origins, you might want to check your eShop account. You might have $20 credit waiting for you, as explained by Nintendo below.

Thanks so much for your support of Batman: Arkham Origins on Wii U.

We are contacting you today because you purchased the Batman: Arkham Origins Season Pass for Wii U. We hope you’ve been enjoying the content that has been delivered thus far. Based on demand for Downloadable Content on the system, Warner Bros. Interactive Entertainment has made the decision to remove its offering of the upcoming new story campaign for Wii U. As a result, we will be crediting the entire $19.99+tax cost of the Season Pass back to your Nintendo eShop account. You will still be able to enjoy the content already released thus far.

We apologize for any inconvenience this may cause and thank you for your support of the game.

Sincerely,
Nintendo of America Inc.

Thanks to Borisoft for the heads up!
