The truth is... Platinum Dunes does not seem to be fond of sequels. They have made a total of 8 films, and have only made one prequel and zero sequels so far. We do know that director Samuel Bayer said he would not return for an Elm Street 2, and that Jackie Earle Haley has agreed to do at least two more films.
There was a lot of talk about a Friday the 13th follow-up that never materialized, and Dunes lost the rights to The Texas Chainsaw Massacre franchise -- basically the company's history says an Elm Street sequel is unlikely. Keep your fingers crossed!
