Re: I suppose they could do a prequel,
The Silmarillion was never written with publication in mind
Given that the first attempt to publish it was during Tolkiens lifetime I somewho doubt that - especially as he himself sent it to the publisher (who rejected it) just after the Hobbit had become popular..
It's true that it was finally published after he died but he had tried to get it published before he wrote LOTR.
