This isn't particularly surprising. And for those about to jump on the "yay Author's Guild" bandwagon, just keep in mind this is the same organization that protested Text-To-Speech rights on ebook readers.
At any rate, that ruling only related to a preliminary injunction. RH and Rosetta settled out of court, so the issue is still officially open. Plus, it's really up to the language in the contracts, which vary from publisher to publisher and almost certainly changed over the years. I would not be surprised at all if earlier contracts do largely favor the artists' rights, but the issue is far from settled.
