That's a fake made up of pictures consisting of the new Mary Jane Watson poster, and some fan manipulations.
From what's been shown (the trailer from the con leaked onto Hype; white eyes, tounge hanging out, large bottom jaw, sharp teeth), and how it's been described, that's not Venom at all.
Just a fan manip. It's circulating the fan manip threads over there and in some blogs.
