Shotwell said it was too early to set precise prices for a reused Falcon 9, but that if the fuel on the first stage costs $1 million or less, and a reused first stage could be prepared for reflight for $3 million or so, a price reduction of 30 percent – to around $40 million – should be possible.

How does "without a doubt" fit with that vague Shotwell quote? (fantastic name to have in the rocket business, by the way)
Let's see how it goes. At the moment it's just guesses and marketing speech.

Addendum:

It is mainly the "[if] a reused first stage could be prepared for reflight for $3 million or so" part that it all hinges on.
Can they really refurbish a first stage for only $3 million?

Come on :) It's about product life cycle basics. http://productlifecyclestages.com/

I try again :)

Is it so hard to comprehend that nobody can tell? :D -Because nobody refurbished rocket boosters on production scale. Final numbers will be known when they get there. Target is 3$mil, but you know, trade secrets and misleading of customers and competition is going on all around us. We will see.

Anyway for all those LEO constellations to come, lots of launches will be needed. We better pray they meet those numbers so we all can have better and lower cost communications.

Some of that may be from the history of the Space Shuttle where the engines had to be completely rebuilt because they suffered damage on every flight.  NASA ended up redefining cracked turbine blades from a failure to a maintenance problem.  If the engines are only designed to be used once, then refurbishment may amount to a complete rebuild.

Presumably SpaceX designed their engines for multiple flights so refurbishing amounts to more testing than rebuilding.  This implies that they could get more performance out of them by operating them to destruction.
