I'm with Larry. They should, and probably will, release it un-edited, but with supplemental material to explain its context.
On a side note, a couple of things make this different than Gone with the Wind, for example. SotS's audience will include many more children, who aren't going to understand the context like most adults would. Also, if anyone wants to complain, they will know exactly who to go to (one of the disadvantages to brand name recognition). With GwtW, most people wouldn't know who to complain to.
That's not to say they shouldn't release it, because they should. I'm just saying they do need to do it with care.
