Based on what Woodley told The Today Show, it would seem that maybe the TV plan is only a possible end to the series, perhaps a big screen wrap up is still a possibility as well.
The fact that she seems to know that no decision has been made is news in itself.
If the star of the movies doesn’t know what’s going on, then it would appear that nobody does.
However, if they had spoken to her, then the actress would at least have an idea of what the plan is.
