I’m pretty sure there’s more bonus material for the prequels in the complete saga Blu Ray set
That could be a matter of them being made in the DVD age where special features are planned for. That didn’t exist in 1977-1983.
Do the fans who really like the PT care about the other cuts? Aren’t they usually the ones who prefer the SEs, or whatever Lucas’ vision is this week?
I’m under the impression they probably just don’t know much about the changes they’ve made to the movies throughout the years.
