I have not seen one replacement host yet that I think could be the permanent host. I have been to dozens of live tapings of the show and Marilyn is as genuine in person as she is on tv. She talks to everyone in the audience and is available to chat after the taping.
I forget how Marilyn was when she started but I'm sure she changed over the years to become the perfect host....someone who we felt was like us...our friend (after all the years of watching Cityline, I felt like I knew everything about her).
The problem with all these new possible hosts is that most of them are too young. I don't think that my friends and I could relate to them. We're all around Marilyn's age. Maybe they need two shows....one for the young crowd just starting families, and one for the over 40 people whose children have left home.
