Maybe someday there might be more footage released of his trip in 1975. We've been pretty fortunate with all the footage released in the last few years. All of that Pumping Iron raw training, posing, backstage, etc, footage has been great. I'm thankful that we have the footage that we do have and confident even more (of the hundred hours from Pumping Iron) will be released in good time. Arnold has been very generous. 
As much as Arnie likes to talk about his past as a champion bodybuilder, he also doesn't like to look back and won't even look at past photo albums. A quote I recently heard from him was that once he's done with a project (e.g. Pumping Iron, a movie, etc), he puts it in the vault and moves on to the next project. So, it's pretty cool that he's agreed to release all of this raw footage and used it successfully to promote his MusclePharm supplements.
MusclePharm is finished.
What Arnie should do is take all the unseen 1975 footage and make a special DVD.
Too bad they didn't make Pumping Iron in 1974, that would've captured Arnold at his all time best.
