On Bleeding Cool there is an advance review of Flashpoint #4. The reviewer compares it to the Harry Potter sport Quiddich in which a field of players compete by flying around and shooting balls through hoops, but there are two players who chase after the golden snitch, and when it's caught it effectively ends the game. The reviewer ends the review with this:
And the book ends, in the midst of the bludgeoners, with a glimpse of, at least, a possible golden snitch.
They even get the colour right.
Could this be a possible Booster Gold appearance? What else is gold that may be able to fix things? Would they throw him into this so close to the end when he hasn't appeared at all in the main Flashpoint series yet? Hard to say but I guess we'll find out on Wednesday!
