I think they should have Topher Grace be Eddie Brock for most of the movie with the symbiotes being introduced through out. Have the villains be Sandman and the Hobgoblin. Then have Venom be introduced as a sort of subtle cliffhanger. Like having Brock entering a church as the movie ends. I wouldn't say that sort of thing; except that if the movies really do end in the 3rd, then there's no way to give all the villains, not to mention the main characters any justice. There is an official picture of Sandman and I thought that I had heard of someone seeing James Franco in a Hobgoblin-esque costume on set. Haven't heard any real confirmation on Venom, just that Topher would play his character. I just kind of think that might lend to my theory a little. I thought I'd throw this out there.
