According to the Home Theater Forum review, it's in SD, as are all the extras except for the shorts.
The scene was actually reinstated for the tv broadcast premiere in the late 80's, so maybe it's sourced from an old video master?
I kind of figured that would happen but one can always hope. I knew about the TV version using the scene but I thought it might be nice to have a version that could potentially be used to make an extended cut.
