According to IESB, Eddie Brock and Venom are going to get their own film.
The site says that since the rights to Venom have reverted back to Marvel (New Line had 'em), they are meeting up with a number of "A-list writers" to work on a spin-off film. (They're not sure on how Sony fits into all of this.) IESB says: "We have to assume that since there is movement, and there has been recent meetings with writers, this property must belong to Marvel since they have made an interim agreement with the WGA."
I had a bad feeling about this until they mentioned the A-List writers. We're fine.
