That being the case, while there will likely be some shows you love listed below, with a couple of exceptions -- where it would legitimately be shocking to see them return -- don't give up hope just yet. A lot of factors will be weighed in the coming weeks, before the networks make their final decisions in May for their Upfront presentations.
Per usual, look for frequent updates to this story, as the fate of more series are decided. I'll also soon be adding some midseason shows that aren't yet listed because they are either too new (Believe, Resurrection) or haven't debuted at all yet. Also, keep in mind this list is for the broadcast network shows only. There are so many cable series, who have so many other elements involved (not to mention are scheduled differently), that we're keeping the focus on ABC, CBS, NBC, FOX and CW here.
Update (3/19): NBC have officially renewed Parks and Recreation, Grimm, Chicago Fire and Chicago PD.
