"Be patient - their next rocket (ITS) will be completely reusable. "

Maybe, Mr AC they will have got the bugs out of full reusability by then, like they said they had when they released that nice video in 2011.

Or maybe not.

Unfortunately ITS is built to put 100 passengers into LEO. It's not just a bit oversized for pretty much every sat ellite planned, it's grossly over sized. So no it won't be any cheaper in absolute terms but SX will no doubt claim it's less than $1000/lb to LEO. Which will be true provided it's fully loaded.

The combination of making it cheaper at the size of payload people want to buy, while swallowing the development bill, is what makes building a fully reusable launch system really hard.

"I think it's more likely that ITS (and cargo delivering derivatives) are operational before we get a working SABRE engine"

Musk said 6 years in 2014 and he thought that was optimistic.

So IRL more like about 8-10 if FH is anything to go by (which remember is only about 2x bigger than an F9 in payload).

REL were very open about what this would cost. You want a vehicle the size of an A380 that can deliver launch on demand and not rely on a single US company to do it for you? Guess what, it costs like an A380.
