What's up with the Vader action figure? Do you think Lucas shot some new footage, maybe dual footage, while he was filming ROTS. Maybe Lucas wanted to make the damage to Vader from the Emperorer's lightning to be more evident, so he shot some new footage of Vader getting electricuted. This would make it seem like Vader definitely died from the lightning. Also, if you look at the Vader action figure's cloak it has holes in it from what appears to be burns, and the helmet looks like it has exploded. The helmet exploding is consistent with an old ROTJ poster that showed Vader's helmet breaking into pieces like it had exploded. It would be very easy to digitally alter the suit and Vader's body to make it look more damaged from the lightning. I know Vader's helmet exploding would contradict the unmasking sequence later on, but I am sure Lucas would try to make his new idea work at the expense of the existing elements and plot. This is just me speculating, because with Lucas you never know what he might do next.
