AFAICT nobody's spotted any differences in ROTJ presentations that would indicate home video got something different.

But Return of the Puggo hasn't been released yet ;) I wouldn't be surprised if we had another incident like PSB's mono mix.

...in fact, I might actually be a little disappointed if it's just a boring stereo folddown =/

* Many slight differences in the 70mm version of ESB (which is not what negative1 has)

...or maybe they do have a 70mm and they just haven't told anyone yet ;)

They'd probably need all new equipment to capture it with, so they wouldn't want to get our hopes up.
