CNN says:

"Sources said the studio is in negotiations with director-producer Sam Raimi (the "Spider-Man" movies) for a project titled "Freddy vs. Jason vs. Ash." In the proposed sequel, Freddy (from the "A Nightmare on Elm Street" films) and Jason (from the "Friday the 13th" pics) would go up against Ash, the cynical anti-hero survivor of Raimi's "Evil Dead" trilogy, which also includes "Army of Darkness."
