As much as I would love to see this happen, the prequels are canon. As long as George Lucas is alive, I don’t think it will happen. It would be a huge middle-finger to say to The Creator, “Your films are so bad that we are going to pretend they don’t exist,” no matter how true that is.
Also, consider that these films are part of what Disney paid billions of dollars to own. Children love them and I cannot see them trashing them.
But god-almighty, I wish they WOULD remake the prequels!
