The news has come down from NBC that Hannibal will in fact get a second season. The second season will have 13 episodes and air, again, as a mid season replacement.
NBC Entertainment president Jennifer Salke said: "We’re so proud of Bryan’s vision for a show that is richly textured, psychologically complex, and very compelling... There are many great stories still to be told."
Synopsis: The series follows serial killer Hannibal Lecter (played by Mads Mikkelsen) in his early days, and his relationship with criminal profiler Will Graham (Hugh Dancy), who has a unique ability to peer into the mind of serial killers.
The next episode of Hannibal airs June 6th, 2013.
