There was an expectation after ESB that Star Wars was going to go on long enough for the actors to grow old in their parts. Weird Al referenced this in his Yoda song.

Starlog magazine even made jokes about their early 21st century incarnation that would come on a computer disk, and feature an interview with an aged Mark Hamill in his Jedi Master costume on the set of the latest episode. They couldn't predict their own demise, alas.

Never heard or been aware of such expectations. As I recall, there was uncertainty Ford would even do a third one at the time, (the character arc of Solo was basically complete by the end of the second film and he hadn't yet signed for a third movie like Fisher and Hamill) reports were that Lucas would make SW movies out of sequence with completely different characters after the third one, even back then.

It checks out

Well, I heard my friends really got in a mess
So I'm gonna have to leave Yoda I guess
But I know that I'll be coming back some day
I'll be playing this part 'till I'm old and gray
