I just don't understand everyone's desire to have these actors back. I can see wanting the characters--if Luke, Leia and Han aren't back in Episode VII, I might have a full-out tantrum--but the actors?
Why? As much as I loved Hamill, Fisher and Ford in the original trilogy, they no longer resemble the characters I grew up with. In order to add them into the storyline, we have to skip at least thirty years of the characters' lives, important years that will have to change who they are. And on top of that, while none of them are bad actors, there are so many better ones out there who would be more than happy to play these roles.
I want a sequel that's set just a few years after Return of the Jedi, when the universe is still just recovering from the Empire and a lot of crap is still going on. If the writers want to ignore the EU completely, fine with me, but we could have such an amazing, new start with a younger cast that can breathe some fresh air into this franchise.
