During the Legendary Pictures panel Guillermo del Toro asked the audience "Hellboy 3?" followed by loud cheers. To which he replied, "Good, because they're listening," and pointed off stage to the Legendary Pictures producers.
Later when Thomas Tull (majority shareholder of Legendary) came on stage he said, "I do want to say, del Toro posed a question, and I'll say, when he's done with Pacific Rim 2, we'll talk."
As usual, don't get your hopes up, but you needn't give up hope yet either.
