I could think of 3 reasons to do them:
1 - to please the OOT fans
2 - to make money
3 - to clear up the legal situation and allow those who distribute OOT rips to be prosecuted.
I think 1 is clearly out the window, they are not particularly concerned about this (indeed Mr Lucas doesn't even believe there is really a demand for them).
2 is a given. They wouldn't do it if it lost money.
So that leaves 3.
I think all restorers who are making an organised effort - like X0 Project - should be VERY CAREFUL come September.
We have seen that the MPAA is getting harsher, tagging along behind the RIAA's "sue the customer to increase sales" tactic.
We have seen that George Lucas has developed a strange loathing for some sections of his fans (maybe all of them).
It seems that LucasFilm are becoming more and more the commercial money-making machine, moving away from their original emphasis on new tech.
So therefore: I suspect that we will see a flood of cease-and-desists and possibly serious legal action against the most visible restoration projects, come September.
What do you think?
