Hopefully the right balance can be found to have the proper inky blackness of space, the deep rich darkness of Vader's robes and so on, and yet retain good shadow detail, the texture of the cloth and such. Though if, due to limitations of the sources currently available, a choice had to be made between more apparent detail in darker areas, but then the black levels being less than they should be and washed out; I'd say having true black levels where they should be and a bit less shadow detail is less harmful to the overall appearance. Hopefully we can have both. :)
