Think about, other then CGI Yoda, what has he changed in the PT on the BluRay release? ...

Yes, apart from CGI Yoda and Skywalker's Mommy's voice added to the AOTS dream sequence it appears not much has been changed.

But as we all know, PT versions on DVD are not the theatrical cuts so LFL has already tinkered with them.

My point isn't an indictment of Lucas but it just shows that the man is never happy.

Even my 5-year-old knows that when the painting is done, you move on to another one. You don't go back and modify or add things - you just move on.
