I feel it would be weird if they teased the person who used to play the role. Like "Find out who is playing Spider-man in the next Spider-man movie!". Uhm, the guy who played him the last time around?
I think the fact that he hasn't played the role in decades does allow for some latitude in them teasing him. If the last Spider-man movie had been almost two decades ago, then getting the original star back would feel like a bigger deal.
