Some sites are citing this as confirmation of the next movie but until we see an official press release I'm treating it as further speculation. Anyway, here are the excerpts from the article in which, while interviewing Nolan about working with Robinov, they seem to confirm the next Batman picture and later let it slide that Flash or Wonder Woman might be one of the next DC characters they focus their lenses on.
"He is trying not to cling to the things that have worked in the past," said Christopher Nolan, who directed "The Dark Knight" and is working on another Batman sequel....
The Walt Disney Company's $4 billion purchase of Marvel Entertainment just over a month ago has increased the pressure on Warner to succeed this time. Warner is expected to announce a DC slate in the coming months populated by characters like the Flash and Wonder Woman."
This sounds to me like it could just be speculation on the interviewer's part after yesterdays announcements that the third Batman film was in the works with Jonah Nolan and David Goyer on board to cowrite the script, and that Christopher Nolan would be over seeing the latest Superman movie. But, either way, with all of these stories popping up, expect official confirmation soon.
