According to a source over at Ars Technica and numerous tweets, Nintendo Power will be coming to an end because Nintendo has chosen to not renew their licensing agreement with Future. The magazine which launched in 1988 was run by Nintendo until it was licensed over to Future Publishing in 2007. With Nintendo Power being one of the longest running videogame magazines, many are sad to see it go.
There may be some good news, though. Over at CVG, there have been unconfirmed reports that a digital future for the magazine might still exist. We can only hope.
