Is there any indication about when the sequels will take place?

I just don't understand how Obi-wan and Anakin aged 40 years in 20 from the prequels to the OT. Now that the actors have aged 30 years means that the story should reflect this change.

I hope that the child of Han and Leia isn't a teenager, is all I'm saying.

But this assumes that the original actors reprise their roles. Now, I would like to see an older Luke like everyone else, but everyone else said that they would like to see a young Anakin Skywalker 20 years ago. I think that a person's imagination does a much better job of aging Luke into a Jedi Master than the slow march of time.

On that note, why does everyone want to see the old characters again, yet also want new characters? For a character to work, they must contribute to the story. The Luke of the OT should not be the Luke of the sequels. The prequels showed us that. One of the reasons that the characters of the prequels failed was because they had to be a certain way in order to match the OT, instead of doing what they would more realistically do in a situation. Jedi Master Luke is not the same character as Jedi Knight Luke. To reprise the role is to concede that the character isn't strong enough to survive without the actor, in my opinion.

Darth Vader is such an enduring symbol of evil because his character is the result of the performances of many actors, including David Prowse, Bob Anderson, Sebastian Shaw, and James Earl Jones, and that's just in the OT. No one actor was Vader. He was a symbol. So was Yoda. Even Obi-wan was iconic, though he didn't need multiple actors to portray his character.

What I'm trying to say with all of this is that if the character is worth bringing back, it's worth looking beyond the actor for the deeper meaning of the character.
