While we are still desperately waiting on the first trailer for Ridley Scott's Prometheus which is expected to have DNA/connections to the Alien franchise. There is development on another iconic film that Ridley will be revisiting. Alcon Entertainment (Insomnia) nabbed the film rights to Blade Runner and were pursuing Scott to direct. Ridley officially joined the untitled Blade Runner film as it's director and producer. It's expected that Warner Bros. who made the original and have worked with Alcon in the past will distribute.
Ridley spoke briefly to Speakeasy (via Playlist) about the film. Scott is considering this project a sequel even though Rick Deckard (Harrison Ford) will likely not be in it. He seems to have found a writer and gives the impression development is further along than we assumed.
"liable to be a sequel.....I think I’m close to finding a writer that might be able to help me deliver. We’re quite a long way in, actually."
"Scott says the new “Blade Runner” project is moving ahead “not with the
past cast, of course.” No Deckard? “No, not really,” he says."
Some possible writers could include Damon Lindelof (Lost, Star Trek, Star Trek 2) who recently worked with Scott on Prometheus adding massive re-writes to the original script. Another candidate could include Travis Wright (Eagle Eye) who was confirmed by SlashFilm as writing a Blade Runner sequel before Alcon/Ridley ever got involved. It will be interesting who ends up writing because we have no idea what angle they're aiming for. There has been talk of continuing the original dectective noir aspect also taking things into outer space focusing the replicant uprisings on off-world colonies.
