Re: Wait, did this movie [SPOILER]
It was an obvious plot device that (unlike Spock's resurrection) everybody could see coming a mile off.
Who couldn't see Spock's resurrection coming a mile off between the Katra thing and the soft landing of the torpedo on the magical life creating planet? Nimoy wasn't a guarantee for STIII yet, but they sure left a big enough hint in case he decided to return.
