As an update, Warner Bros. Interactive Entertainment, Rocksteady and our partners are targeting an interim patch update for existing players to be released in August. This update will address many of the issues we listed in our June 27 update. We will provide additional details as we finalize that interim patch over the coming weeks.

We would like to thank you for your continued patience and invaluable feedback. We are continuing to monitor and listen for any additional issues and are driving towards a full update for everyone as quickly as we possibly can.

The wait continues but at least it won't be as long as the rumors suggested.
