Batman: Return to Arkham New Release Date?

For those who do not know, Batman: Return to Arkham was delayed indefinitely, which means the game was delayed with no release date in sight, but an email was sent to those who pre ordered the game at Best Buy saying the game was due to release September 2, 2016, but some WB executives say that the earliest the game will be released is around November, so the latest could even mean early in 2017?
