Release date is probably Q1 2016, as per their old press release:
Fiscal 2016 is off to a great start, highlighted by the April launch of Grand Theft Auto V for the PC, which has exceeded our expectations. Throughout the coming year, we will continue to execute our proven strategy of launching a select array of the highest-quality titles, led by new annual releases of NBA 2K and WWE 2K; Battleborn, a groundbreaking new intellectual property from Gearbox Software; and a soon-to-be announced new triple-A title from 2K.
