Who is the enemy of Spiderman in Spiderman 4?

To start of with, there is not going to be a Spider Man 4. If there was, it would've been vulture. Sony was pushing Sam Raimi (direcotr of spiderman) around, so he got very angry, and left spiderman. So sony is making a new spiderman series with new acotrs and a new director. It starts of with peter parker back in high school. The series is going to be called the 'Amazing Spiderman' and is subject to release in 2012.
