ED4, will Bruce Campbell return...

Yes, if Sam Raimi has anything to say about it...

"He can dream all he wants. He's trying to get out of getting back in shape," says Raimi, "I'm going to kick his butt in shape. I'm gonna say 'get back in the chainsaw!'"

So will Sam Raimi ever commit to making Evil Dead 4?

"I hope to, yes," Raimi admitted, "Every time I say I would like to [revisit the films], people say, 'where the hell is it!?!' But I'm just glad people are still interested. But yes, I would really like to do [another 'Evil Dead' film]. I've just got a commitment to make 'Spider-Man 4' right now though."
