I think a lot of it depends on whether they can make the reuse of the second stage work without having to redo stuff constantly like the shuttle. Reusing the booster will obviously save tons of money and make launches cheaper, but they're competing with themselves here. How big is the launch market with cheaper launches? We don't actually know.
