I recieved my issue of Nintendo Power today with a... Well horrible letter as the front of it.
The front letter was from Reggie Fils-Aime and Chris Slate informing all the subscribers that as of the December issue Nintendo Power will no longer be published.
The letter does state that the WiiU will offer channels for game information however in place of Nintendo Power.
On the NP website it says this:
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.
