Here's part of the interview where Sam Raimi hints about Bruce Campbell's return to the franchise:
Raimi: “For the first time in his life Bruce is an in-demand actor – at age 50”, laughs Raimi, who also worked on the actor on such films as “Spider-Man” and “The Quick and the Dead”. “He’s on a show called Burn Notice – which is really funny, and he’s great in it – and the week that I wanted to use him, he was busy doing that, so I couldn’t. He was just too in-demand, but we will try and get him in the next – probably Spider-Man 4, I’ll find a part for him.”
Moviehole: “Spider-Man 4” you say, Sam?
I think he'll return as Mephisto, but then again he could return just to make a cameo since Raimi tends to put him in almost all of his movies.
