A Blade Runner sequel

Harrison Ford will reprise his role as police officer Rick Deckard in the forthcoming Blade Runner sequel, it has been confirmed. The story takes place several decades after the conclusion of the 1982 film, which was based on Philip K Dick novel Do Androids Dream Of Electric Sheep?

Not sure how I feel about this. How could they ever better the original? Even coming close would be a monumental undertaking. Like making a sequel to Citizen Kane.
