Is that Palpatine pic on Coruscant right before "mechanical" Vader's birth?
I believe so. During the Rick McCallum Spectacular, they showed a shot of a shuttle heading toward a building on Coruscant in the rain and I'm guessing that Palpatine shot is shortly after that.
Yep, he's parading in walking with some troopers, and behind a medical floating board that is carrying Anakins body, Anakin is kind of breathing and writhing around slightly.
It kind of mirrors Padmes death scene where she to is paraded on a floating platform (maybe casket)
