Well, it turns out that there’s a good reason according to Roth, but it may upset book fans:
“What does this mean? Well, basically, it means there are going to be some changes, but it’s really too early to know exactly what those changes will be or the extent of them. I know changes always make fans of the books– and the author!– nervous, but hopefully the characters we know (and love. Or sometimes love to hate?) will still be intact, which is really the important thing. I am eager to see how these movies turn out, along with you guys.”
The Divergent movies haven’t taken off in the same way as The Hunger Games either critically or from a box office standpoint, so how these will turn out remains to be seen.
The Divergent Series: Allegiant is set to be released on March 18th, 2016 and then The Divergent Series: Ascendant will follow that on March 24th, 2017. Here are those logos:
