I can't believe this is even a debate. Of course Sony wanted to make Spider-man 4. They set a release date, got the principal actors back and had Raimi working rigourously on a script. I don't care what the critical reaction to Spider-man 3 was (which was never as bad a fanboys like to make out), the movie made just over $890 dollars at the box office. It was a huge success where it counts. The reboot notion only started drifting into Sony's head when the production became troubled... thus Raimi feeling the divide and pressure left.
