Back on topic, as far as this version of TFF goes. CBS needs to figure if this version would be worth it to package, market and sell it. IMO, it stands a better chance of selling than some of the repackaging of the same Star Trek films that they are always doing ( "the all new blue package of ST:TFF complete with a Sybok refrigerator magnet!"..yawn..lol)
I think this will serve more as a "proof of concept" than the actual product. If CBS sees value in the changes then they will then hand it off to a company to make changes in concert with Shatner.
I seriously doubt a fan-edit will ever be released as an official product.
