According to this official tweet, Williams is only confirmed for Episode VII at this point. However, Kathleen Kennedy said he was scoring all three films. Even SW Insider said he was scoring the entire trilogy. Wonder what has changed since then or if the official tweet was mistaken? Very confusing...

The guy is over 80, they probably don't want to put too much on his plate at once. Taking it one film at a time is better. I just saw him in concert in Boston the other week, and he's still doing great (and even mentioned the new trilogy). I'm not worried about it.
