These plans have not changed, as Bloody Disgusting reports that the Weinstein Company is going to take Halloween 3, which was initially slated for a 2011 release date, in a new direction and are currently "open for pitches." Patrick Lussier and Todd Farmer, who worked on My Bloody Valentine 3D together, were originally slated to bring Michael Myers into the third dimension, but as B-D notes, whether or not they're still attached to the project is anyone's guess.
While I'm sure the film will eventually get made, we can only hope they decide to eschew the third dimension in favor of, you know, a good story and competent acting. 3-D works in only a limited number of scenarios, and a slasher film is NOT one of them. I don't care how many eyeballs or pick axes get thrown at the screen, it ultimately serves as nothing more than a distraction.
