I’ve heard that she is not coming back for Season 11.

I think SHIELD will have a significant impact on NCIS’s ratings (especially in the all-important 18-49 group) whether Ziva is there or not. And Big Bang Theory may take over as the most watched show as well. I’ll be DVRing both NCIS and SHIELD, but it’s SHIELD that I’m looking forward to watching (the previews look great!).
Whether Ziva stays or goes, I just think NCIS has gotten stale. They’ve been pushing Tiva for eight years now, and the Mossad story lines for at least 5 years now. They need to move on, freshen this show up, or close it down.

Anna — er Jo — I have been watching NCIS since the beginning. I’ll continue watching whether de Pablo returns or not. But I totally reject your defining a true fan as somebody who quits because of the character Ziva remaining with the show. If that’s your definition of a true fan of this show, then why didn’t you, and the others who subscribe to this belief, quit after Season 3?
Incidentally, ratings for NCIS usually dip during the months of March, April and May. They did so back in Season 6, Season 7, Season 8, and Season 9. What remained the same was the thing that the network cares the most about, that being that they won their timeslot.

What about the fans who say they are not going to return if Cote comes back, or if the show puts Tony and Ziva together as a couple? I guess that means those folks will finally, after 8 seasons of complaining, finally quit watching? Will they be missed? One has to wonder, as they have complained nonstop and yet the things they have complained about are as much of the show as ever, if not even more so.
Oh, and while “Shiva” was indeed about the aftermath involving two characters who were killed after having been invited to Director Vance’s house by the director himself, thus, sadly, helping to set the stage for his wife’s tragic death, the episode was advertised as being primarily Ziva centric, with the focus in the advertising containing scenes of her, and with more than a hint of Tiva, showing her waking up in Tony’s bed.
If you’re going to bash, get your facts straight.

Probably Jo.

Or would guarantee that they get blown out of the water by “S.H.I.E.L.D”.

Since you seem to be privy to the negotiations going on between Miss de Pablo and CBS, unlike many seasoned, veteran reporters who cover the entertainment field, perhaps you will share with us just what some of those “absurd demands” are?
