"Another problem with a movie is that so many characters died in the last season. Chase said he has considered "going back to a day in 2006 that you didn't see, but then (Tony's children) would be older than they were then and you would know that Tony doesn't get killed. It's got problems."
So I think that means he does want people to think Tony is dead.
Personally I think it's a load of horseshit. Stories should have endings. That's all there is to it.
