But that's considering that they actually go ahead with a Venom spin-off in the first place. ...
I would think Sony would want to see how SM 3.1 was received before making a decision on a Venom movie. From what I've read so far, most people are sour on a Venom movie b/c of of how SM3 had limited Venom screen time & then had Brock killed off.
Maybe a 3.1 would change people's feelings on a Venom movie. The fact that we're still writing about the deleted scenes, and the amount of them, shows that there is great interest in a 3.1.
In other words, give us the FULL VERSION of SM3 in an extended edition, and then we'll consider supporting a Venom movie.
I don't know of many comic-book-based movies coming out next year, so maybe 2009 would be a good time to release a 3.1? 2010 would be crowded.
