I just spoke to Karl about it the other day (and have video).
There are several issues:
- Money to get it finished, in terms of extra research. He said it would need a full time person 6 months to finish that.
- Money to get rights to use certain stock images etc.
- Approval of people for use of their material. Many of the big business people are still holding out on this.
- He works for a living, which means he is very busy.
- The fact that he's a professional film maker and has a big industry reputation to uphold, which is why he can't release a hack'n'slash version, or just dump what he's got now.
- He's a perfectionist and it's his pet project :-> It's kinda like my USB power supply and other projects. I always come up with new direction to take it, so it never gets finished...
He currently has 6 hours of fully edited and essentially complete footage.
