Since what's been done to THX-1138, I wonder how any future historians are going to sort it all out. We are on the third version of the SE's and now the second iteration of the prequels.

And if anyone who knows copyright law could chime in, how do the 2004 and 2011 changes not require an updated copyright? Besides the fact whoever did the new shots don't get any onscreen credits, there are credits for people whose contributions have been "deleted". (Clive Revill in Empire, and now the assistant Yoda puppeteers in Phantom Menace.) A new credit roll ought to be the easiest thing to change, and they don't do this.
