Will the DreamChaser wings have much clearance inside the fairing, I've seen this issue raised as a concern with the X-37B & the F9?
X-37B's are fixed position like shuttle, whereas DC Cargo Version Folds up where the wings meet the fuselage thus there is DC Cargo is within acceptable fairing parameters and limits.

That's a neat solution.

Besides allowing for cargo pod it also eliminated the aerodynamic issues that exposed DC with fixed wings would've created.

Will the purchase price be public?  That would provide some insight into the current cost of an RL-10, since one more of these engines is the main difference between a 552 and a 551.

I wouldn't expect it to be public.  SNC is buying the launch, not NASA.  Did O/ATK ever give a cost for their Atlas V purchases?
yes, only to certain Investors and financial/capital analysts but was after IR conference calls so that the info was not in public recordings and transcripts.
Interesting.  This sounds like it would be the definition of illegal insider trading if the investors or analysts act on this knowledge.

The cost of the rocket is surely material to any analysis of profitability of that contract, and the contract is certainly very material to Orbital.

OrbitalATK's prices for CRS2 were made public. See this link:

The planned Atlas V 552 configuration was shelved when a decision was made in August 2019 to have the Dream Chaser spaceplane launched from the Vulcan, in which case all Dream Chaser orbital flights are intended for launch from the Vulcan.
