E3 2016 - Injustice 2 Official Trailer
Warner Bros have just announced that Injustice 2 is real and will be coming to Xbox One and PS4 in 2017 (no PC from the announcement but it's possible they could add it later).
Most of the characters seem to be the same as the original game (apart from Supergirl which makes her Injustice debut) but we're promised brand new villains in the shape of Gorilla Grodd and Atrocitus.
The big new feature is the Gear system which let's you customize your fighter the way you want and obtain gear which others may not have, as you get more gear you'll be able to further power up your character.
While the lack of PC support seems to be worrying it's still possible it might happen eventually, they rushed out Arkham Knight so a PC version may be in the works.
