I found this pretty cool chart that pretty accurately predicts the chances that TV shows will be canceled or kept. Keep in mind none of it is a guarantee just guesses and this is almost a week old now so things have changed.

Just a couple corrections/updates to the list:
“Life”, “Prison Break” and “Terminator:TSCC” are not being canceled in May. All three have received full season orders and are likely to be canceled in May unless the either the shows’ ratings improve or their respective network’s ratings continue to fall.
“My Own Worst Enemy” and “Lipstick Jungle” have been canceled. “My Own Worst Enemy” might not even get to air it’s remaining episodes.
All in all it’s still kind of hard to predict what’s going to happen with some of these shows. TV ratings have been down and dropping since returning from the strike which might help out some of the shows receiving sub-par viewership.
