Actually, "Contagion" is in post-production. Which means they're done filming.
There have only been 2, maybe 3 seasons that ended with a "team moment"--Season 5, Grave Danger and Season 8, For Gedda. Season 1 was Sara and Grissom as were seasons 2, 6 and 7. Season 4 was Grissom. I'm not sure about season 3.
Actually
Season 1: Team moment they were all eating breakfast
Season 2: Grissom discovers he's losing his hearing
Season 3: Griss has the surgery and Catherine discovers Sam is her father and what he's done
Season 4: Sara DUI
Season 5: Nick kidnapped, they find him, Grissom tells Ecklie he wants his guys back
Season 6: Brass shot/surgery and he pulls through, everyone was there to see him, GSR revealed to audience
Season 7: Sara kidnapped, everyone is trying to find her, GSR revealed to the others
Season 8: Warrick is cleared of murder and team goes out to breakfast and Warrick is soon shot
Season 9: Ray shoots a guy in self defense
Season 10: Dr. Jekyll revealed/killed, Nick shot but makes it, Haskell stabs Ray
The spoiler says that Haskell is "vanquished" and Ray was the one that did it, as he's going to be investigated by IA. So he's not going to die. Soy sorry to all you wishful thinkers.
I read something awhile back when Fishburne signed on to do CSI, that doing a TV series would enable him to spend more time with his baby daughter vs. having to go on location for movies all the time. So that part about wanting to leave CSI to go back to movies and theater isn't quite correct. Again, wishful thinking on the part of the folks who want to see him gone.
We don't know for sure how things exactly go down with Ray/Haskell, we all probably have some idea, but we don't know for sure yet
And Ray doesn't necessarily have to die to leave, Grissom, Sara, Wendy, Sofia, and Riley all left and they're still breathing
One more thing. It really bugs me when people claim to know what the "majority" of the fans want. How does anyone know this?
Some or I at least I do sometimes think of Talk CSI as how a majority of fans feel about the show
