"SCRE4M" Has Sub-Title?

David Arquette, who plays Dewey in the "SCREAM" franchise let slip that the next installment in the box-office smash horror franchise could have a sub-title. And that sub-title is, "SCRE4M: Return To Woodsboro". Now that sub-title was used in "SCREAM 3" in 2000, for the fictional "Stab 3: Return To Woodsboro".
If this sub-title is for real, then it's the first film in the franchise where the film has a sub-title. It's not a great sub-title. It really sounds cheesy. I really hope it's not true.
