We all know that November is most likely the month for Wii U release, but now we're hearing that there are some issues in Europe due to manufacturing. Some sort of production line problems are forcing Nintendo to push the system's release back in Europe until December. At one point there was talk of a 2013 launch for Wii U in Europe, but it seems Nintendo has managed to salvage a release for this year.

Nintendo has declined to comment on the issue, so we'll leave it marked as rumor for now.
