I'm not sure which email you are referring to specifically: I will PM you about it.
Our goal is to have the film ready for theatrical release in early 2106. However, we are still looking for additional early footage and continuing to add interviews. The production process may take longer than originally anticipated, but we want to make sure we are doing this right.
Keep in mind that having the film ready for a theatrical release is different than having it ready for physical production on Blu-Ray and DVD, especially since those will contain additional features.
As we get closer to a finished product, we will be able to give more specific info about the release dates.
