According to Sci Fi Wire Raimi just told a group of reporters that he is set to meet with Dunst to talk about her reprising the role.
They also asked Raimi if Spider-Man would go the edgy route to align with The Dark Knight and Watchmen. He doesn't rule it out, saying it's really up to the screenwriter.
Edgy could be a direction, but I don't think it will be applied without really understanding the character's journey from the inside out first and then figuring out the best way to bring that about.
What Raimi really wants to do is explore the nature of Peter Parker and what makes him a unique and human character. That's fine as long as he doesn't start crying again.
