They're calling it "Dragon V2"
Elon Musk expects an unmanned test flight by 2015, with a manned flight by 2016. If they're as consistent with this as they have been in the past, we'll probably start seeing manned Dragon flights on a reusable Falcon 9 by 2018.
It occurs to me that the first reusable space shuttle was named "Enterprise." Perhaps the first commercial space capsule should be named "Millennium Falcon"?
