2K Games and Firaxis Games released an announcement trailer for their PC only (for now) XCOM 2 which was official unveiled yesterday and will release in November 2015.
About XCOM 2:
In XCOM 2, the roles have been reversed, and XCOM is now the invading force. They are hampered by limited resources and must constantly evade the alien threat in their new mobile headquarters. Players must use a combination of firepower and stealth-like tactics to help XCOM recruit soldiers and build a resistance network, while attempting to expose the evil alien agenda and save humanity. XCOM 2 will introduce gameplay features such as procedurally-generated levels, which will make each experience unique to the player, as well as offer a much deeper level of modding support. Additionally, XCOM 2 will offer a variety of new content including five updated soldier classes, increased soldier customization, more alien and enemy types, evolved tactical combat and more.
