Here are a few reasons why this might be the case:
* Tour Timeline: The "Dignity" tour occurred in 2007 and 2008. It's been a significant amount of time, and the demand for a DVD release might not be as strong now.
* Content Availability: While there might be some fan-made recordings of the tour, it's unlikely that there's official footage that could be compiled for a DVD release.
* Focus on Other Projects: Hilary Duff has been busy with other projects, including her acting career and music.
However, there is still a chance! It's possible that a DVD release could happen in the future, especially if there's significant fan demand.
You can:
* Keep an eye on Hilary Duff's social media and website: She might announce any plans for a DVD release there.
* Join fan communities: You might find other fans who are also hoping for a "Dignity" tour DVD release, and you can share your desire together.
* Request a DVD release: You could try contacting Hilary Duff's label or management company and express your interest in a DVD release.
While there's no guarantee, it's worth keeping an eye out and voicing your support for a "Dignity" world tour DVD!
