Sad to see it go I have my collection still from 5+ years ago. Use to get so excited when I would come home from school and see my new NP magazine arrived! Once Future took it over I unsubscribed, it just wasn't the same.
Nintendo has confirmed that the December issue will be the last. My oldest son is very sad about this. He loved it and looked forward to every issue. Also our subscription was good through March. I don't know if they are going refund anything or not, but they ought to.
