They say it's "actual flight design hardware". Probably not quite ready to chuck at the ISS, but all the pieces are there. The main differences from the already-operational Dragon seem to be: - improved heat shield (presumably a minor iteration) - docking hardware (OTS) - Super-Draco thrusters (recently flight-qualified) - seats (apparently extant) - piloting controls (apparently extant, may require additional software) - life support system (?) - software for propulsive landing (will require testing, but they can already do it for a 10-story F9) - software for autonomous docking (unknown, but if Soyuz can do it, so can SpaceX) Most of the hardware seems to be ready to go; the software may not be, but that can be done a lot faster than hardware, and nothing here is beyond their already-demonstrated abilities. There is certainly plenty of testing to be done on the novel things like launch abort and propulsive landing (much of which is already scheduled!), as well as on-orbit tryout of a few things. But it looks like it's pretty far along, and I bet we'll see it in space within 12 months.
