Something else to look for is the name of the theatre where "Wuthering Heights" is playing is called Densmore. Which is the name of the street in Van Nuys where WOT Inc was set up. WOT Inc was the production office and visual effects company that first started work on the movie.
I too had heard there was suppose to be a new version, but I also heard the rating weren't that great for Children of Dune. So, they may have dropped the idea just because of that.
