Breaking: The latest pickup/cancellation buzz is here!

Image Credit: Nigel Perry/The CW; Richard Phibbs/The CWWarning: The following info is purely speculative and should by no means be taken as gospel. We’re heading into upfront week, people, and rumors are flying fast and furious. Here’s what some of the loudest chatter is centered on…

• The CW is said to be strongly considering renewing both One Tree Hill and Life Unexpected for 12 episodes apiece. Among new shows, the Nikita reboot is a lock, Scott Porter’s Nomads is flirting with a possible midseason order, and ASP’s The Wyoming Project is… generating absolutely no buzz.
• As NYMag speculated (and Greg Grunberg all but confirmed with his cryptweet), Heroes is likely dead.
• Barring an eleventh-hour about-face, NBC will be bringing Chuck back for a fourth season. THIS JUST IN: It’s official!
• Sources close to Law & Order tell me that NBC will likely shoot down Gunsmoke‘s record and renew the mothership for a groundbreaking 21st season. THIS JUST IN: Or maybe not!
• All signs point to ABC picking up Shonda Rhimes’ doctors-in-paradise medical drama Off the Map, although the boss lady herself just told me she isn’t counting her chickens just yet. “People like it, it [tested] well, but you never know,” she admitted. “I really liked Inside the Box last year and it didn’t get picked up.” THIS JUST IN: ABC picks up three comedies, including the Matthew Perry sitcom Mr. Sunshine.
• SPOILER ALERT: This doesn’t concern upfronts, but a crazed gunman is making a beeline for Seattle Grace. Click here for details!
• Industry sources are giving Fox props for yesterday’s pickup of ambitious dramas Ride-Along and Lone Star. “I hope people aren’t missing the significance of a network like Fox pushing ahead with two projects like this,” acknowledged one veteran TV producer. “The fact that Fox is giving both shows a shot is an important thing for quality television.”
