Liam Neeson and Mark Wahlberg have reportedly been offered lead roles in the movie. The budget is claimed to be $60M.
There is a further link to a recent io9 interview with William Gibson in which he discusses the novel and the film.
I haven't yet found any info concerning a timeline for the film's release, thought it still seems to be early days in the production cycle.
I also found a page of cool Neuromancer concept art at the website of BlueSunCorp, though I have no idea if they have any connection to the film or not.
