Grimm, Chicago PD, and Chicago Fire have all been renewed for next season. Grimm anchors Friday for NBC, while Chicago PD has proved to be a promising spinoff to Chicago Fire.
In the coming weeks, I expect there to be renewal announcements for a few other NBC shows, including About A Boy, Law and Order SVU, Community, and Revolution. I do expect Community and Revolution back, but neither will have full season orders. Revolution might even get paired with Grimm on Fridays.
