It appears that the panel for Batman v Superman has started, and although I cannot get any footage of it, they have apparently released a teaser for those in attendance. From what I understand, the teaser starts out with Batman in a different Batsuit than they have shown us, a metallic suit this time (those of you who have seen the animated film Return of the Dark Knight should have an idea). Batman takes a tarp off the Bat Signal, and as he turns it on the audience sees Superman, glaring at Batman, hovering in the light. My guess is that the picture that they released of Superman from the upcoming film came from this scene. Unfortunately the only picture I have been able to find is this blurry one (pictured below) taken from a phone in Hall H. Hopefully I’ll be able to bring you that teaser soon.
