I'm guessing that the story is going to follow the first movie more than the Philip K Dick short story, but look at the city scenes, they are gorgeous. The special effects in this film look stunning.
Reminds me of Bladerunner with the grittiness and 'real life' feel.
The CGI looks like it was done in London. There's a sign which says 'Camden Town - Keep Left', that's based on a real road sign.
