The Hollywood Reporter states that BBC4 has a new Tale of Two Cities in the works! It's being written by Alan Bleasdale, who did the 1999 Oliver Twist miniseries, and produced by the company that made Parade's End. Netflix is in talks to co-produce.
Bear in mind that the feature film adaptation scripted by David Farr is still (presumably) in development. So we could see another Great Expectations situation, with adaptations coming to the big screen and the small screen at around the same time!
