Sega has announced that Sports Interactive's next footie management sim, predictably called Football Manager 2018, will see release on November 10. Furthermore, if you pre-order the game via Steam you'll get at least two weeks of premature access via the beta that will run up until the full release.
The first details on the new features of Football Manager 2018 won't be released until late September, but you should probably expect all recent developments such as Neymar buying out his contract at FC Barcelona, and the Premier League's desire to move forward the closure of the transfer window so that the window is closed when the season starts, to be featured in some fashion.
Football Manager Touch 2018 (PC, Mac, Linux, iOS and Android) and Football Manager Mobile 2018 (iOS and Android) will see release on the same day.
