Nintendo of America confirmed to us that Nintendo Power is ending, with its final issue being the December 2012 issue.
Nintendo's official statement read: "Nintendo can confirm that Future US will end the production of Nintendo Power magazine with the last issue slated for December 2012. For Nintendo Power subscription inquiries, please visit nintendopower.com/customerservice. Check out Nintendo at nintendo.com, on Facebook at facebook.com/nintendo or on Twitter @nintendoamerica."
A company spokesperson told Ars Technica, who broke the story yesterday, that "Nintendo Power magazine is closing and is not moving to a new publisher. We have nothing further to announce at this time."
Nintendo Power will reach 285 issues as of December 2012.
I always meant to subscribe, but I never got around to it. See where procrastination gets you, people?
Now I'll live my life always wondering what could have been...
refunding of subscriptions and such.
Nintendo Power's last issue will be the December 2012 issue, which will be mailed to subscribers in late November and sold on newsstands starting December 4.
If you are a subscriber and your subscription extends past the final December 2012 issue, you will receive a refund or credit card credit of the remaining value of your subscription. If you reside in the US or Canada, your refund will arrive within 4–6 weeks after the December 2012 issue; for customers outside the US and Canada, your refund will arrive 6–10 weeks after the December 2012 issue.
