The downside is of course, treating the OTs as bonus features. The PT movies all got a two-disc set with tons of bonus goodies.
And when the 2004 OT was released, we got 3 movie discs and 1 bonus disc. 4 discs as opposed to the 6 disc PT.
So, now, with this great opportunity to redress the balance with each OT movie getting its own bonus disc, LFL goes and screws it up by making the OT the bonus. Aaaaaarrrghghhh!!! What about all of those great BTS features that the fantastic people on this board have done amazing jobs of preserving. Everything from the Executor boxset and beyond. Why don't they offer heaps of money to OCPMovie and Jambe for the rights to Deleted Magic, Building Empire, and Returning to Jedi ?

A wasted opportunity.
Yayy. I get the 2004 discs again !!!!
Nevermind. I don't know why I'm surprised.
Still, glad to get an official release of the OT on DVD - better than nothing. But I am glad the preservationists on this board do what they do.
