Well, Volume 3 is the start of RWBY turning darker, so says Miles and Kerry (They equate it to being as if Harry Potter skipped books 2-5), but I think they meant that in terms of the concepts that the story will be showing us, considering that Gray said at a panel that there are things in the plot that are going to force RWBY to be more mature of a show.

But I don't think that it'll turn full-on Attack on Titan gore mode.
