I think Cindy will play a somewhat major role this year, I just cant see her as the "main" Icon. Like people have previously mentioned, what the theme is comes down to how much money they'll make and they want to bring in as much people as possible to get that money. So im pretty sure they would put someone thats a lot more recognizable like Jack or the Caretaker or even the director to advertise the event. People dont know who Cindy is because they have never seen her at the event or even heard about her. Maybe less than 13% of the people that went to HHN last year saw her, and were the only people to have seen her. So if it really is going to be a reunion year, then yes. I think and hope we will be able to see her.
Personally, I chose all the icons. If its going to be a reunion year, why not have them all. Maybe even have a closing ceremony in which they are all finally laid to rest or something.
