Remember the Freddy vs Jason flick ? did it END for good ?? or can there be sequel !??

If there is one thing I've learned from all the slasher movies I've seen, it's that a sequel is ALWAYS possible. Look at Halloween. Everyone thought that H20 was it, but the demand was there for another one. So they whipped up a quick explanation, and POOF, Michael's back to finish off his sister and return home to battle it out with Busta Rhymes.
