Maybe. or maybe his bosses departure.

They added a seat, which means one person could be setting up to leave. (read, smooth transition of power on the board)

If he does leave that leads me to ask two questions.....
1) Where would he go? JAL
2) How long is RA thinking of staying?

There is always movement of the top after the successes they have had. I always assumed that the top would go and many would move up. You could be correct though. Timing is right on the money either way.
