Gossip Girl, America's Next Top Model,90210 and Vampire Diaries were told they are 100% safe and could receive early renewals for next season.
Supernatural is also considered relatively "safe", there are some issues with its age making it slightly less safe in the above shows, but it is much more likely to be renewed than cancelled and could also make an early renewal.
The CW on the other hand told producers of Hart of Dixie, Nikita, Ringer and surprisingly The Secret Circle that they are "on the bubble". Their fates will likely depend on how much the CW likes their pilots and how many new shows they are willing to pickup.
Nikita producers were told they may be given a decision early so they can write a series finale arc in the final episodes.
