In an open letter on the Warner Bros Games Forums, Yorick (Community Administrator) apologized for the unstable launch of Batman: Arkham Knight on PC, stating that it was not Rocksteady's fault for failing to adequately port the game. Until the game has reached a level of quality that Rocksteady is happy with the game will remain off of the digital storefront. The poor reception has also caused WB to change the policy internally for how the company reviews PC games. And lastly don't expect any DLC for Batman: Arkham Knight's PC version to release anytime soon, as the post closes with,

Our continued focus on getting the right PC fixes in place for the main game has had an impact on the development of all DLC content for the PC version of the game. This means that the Batman: Arkham Knight – Batgirl: A Matter of Family DLC will not be available on July 14th for those who are currently playing the PC version of the game. We apologize for the delay and only want to make sure that any content that we offer is up to the standards that PC players expect.
