Time to break out the handkerchiefs and wave good-bye to Dr. Raymond Langston: 'CSI' star Laurence Fishburne has decided to step down from the long-running procedural drama.

Deadline.com reports that after two seasons with 'CSI' Fishburne decided not to renew his contract when it expired in May. He is now expected to return to his movie career full-time.

'The Matrix' star was hired in 2008 as a replacement for William Petersen, and his departure leaves 'CSI' producers and writers with a major headache right before production's due to start on Season 12. Although Paul Guilfoyle is expected to stay on, some actors are still in contract talks, and Marg Helgenberger has said she will appear in only a few episodes next season.

Many 'CSI' insiders were reportedly unsurprised by Fishburne's decision, with one saying: "Nobody expected him to be on the show for seven years, it's Laurence Fishburne."

However, he did recently tell 'Entertainment Weekly' that he wanted to stay with the show. "I'm having a great time,'' he said, while acknowledging that replacing Petersen's character of Gil Grissom had been a challenge.

CSI is teasing us with the diner photo you see above (a much larger version is here, complete with its own magnifying glass). During the program last night, a promo aired that said the clues to the final two episodes are in this photo. Well, I always sucked at Where's Waldo, so I'm seeking out your help.

What clues do you see?
