From: http://spacenews.com/sierra-nevada-weighing-options-for-launching-future-dream-chaser-missions/"SNC held the briefing in front of the Dream Chaser engineering test article that performed a glide flight at Edwards Air Force Base in California in November. That test article, developed under earlier NASA commercial crew awards, will now be placed in “flyable storage” at the company’s Colorado facilities.Lindsey said the company will likely keep the test article in storage until the company is ready to resume development of a crewed version of Dream Chaser. “We’re going to keep it in a condition ready to fly,” he said. “We’ll modify it for flying crew, put a pilot in there and do some testing in the future.” "Previous statements made this week indicated that 80% of the 0.75 cargo version will be compatible with the potential manned Dream Chaser - it would be wonderful in my opinion if a paying customer came forward to complete the development of a manned Dream Chaser.

I thought they were identical in size.I thought the .75 version was only ever talked about for potential use with Stratolaunch.

Not a scale down.

It looks like only one cargo DC will be made:http://spacenews.com/nasa-will-pay-more-for-less-iss-cargo-under-new-commercial-contracts/

Some interesting stuff on DC:Quote from: page 20 of the OIG reportSpecifically, Sierra Nevada has committed to using Atlas V launch vehicles for its first two cargo resupply missions but the company is considering alternative launch vehicles currently under development to lower their costs for future NASA missions. Public statements from launch vehicle providers have proposed prices ranging from roughly $90 million to $120 million per launch. While the Atlas V is highly reliable with a 100 percent success rate after more than 70 launches, it has a list price of $175 million for the configuration needed for Sierra Nevada’s missions. Because Sierra Nevada’s cargo flights are procured under a fixed-price contract, any reduction in its launch costs accrue to Sierra Nevada’s benefit. However, the CRS-2 contract allows NASA to renegotiate mission pricing if a contractor uses an alternative vehicle. Any renegotiation would need to be finalized by early 2019 should Sierra Nevada plan to use an alternative launch vehicle for its third CRS-2 mission, which could occur as early as 2022. NASA’s CRS-2 contract with Orbital ATK has similar contract language to negotiate lower per-mission prices to reflect cheaper launch costs if the company uses ULA’s Vulcan launch vehicle instead of the Atlas V.

More on DC:Quote from: pages 27 and 28 of the OIG ReportSierra Nevada’s plan to build a single Dream Chaser spacecraft for CRS-2 missions is a single point-of-failure that represents substantial technical and schedule risks for the ISS Program.[69] During a visit to Sierra Nevada in June 2017, company officials told us they had no plans to build a second Dream Chaser. In August 2017, ISS Program officials said Sierra Nevada was considering building a second Dream Chaser to be completed by 2021, but no decision had been made as of October 2017. In the event of a failure, Sierra Nevada officials told us in June 2017 that a second spacecraft could be built from spare parts without additional costs to NASA.[69] For the first CRS-2 mission, the Dream Chaser will be required to demonstrate additional orbital maneuvers before approaching the ISS. Other cargo vehicles such as the Cygnus, European cargo spacecraft, and Japanese cargo spacecraft were allowed to berth with the ISS on their maiden flight after performing similar maneuvers.
