Where to start. You are making huge assumptions and talking about a period way in the future. Just about everything you are saying here is flawed as a support for the prospect of a new AvX.
Hickman has a long term plan and seems very convinced he knows how to keep interest going based upon his recent interviews. We are not talking about afterwards anyway. Why worry about something that will happen 3-5 years away when the status quo will be totally different and unpredictable.
Remember, Hickman was brought in by Buckley not JDW. It is much harder to sack him.
