Point 1: Injustice: Gods Among Us wasn’t announced for PC either. And yet, here it is. The same goes for Mortal Kombat IX. In both cases we got the Complete Edition with all the DLC, and they mostly worked fine. The only time NetherRealm have released a game for PC day and date with the consoles was Mortal Kombat X, and that did not go down well.Point 2: There’s still a year to go. Injustice 2 has a vague release date of “2017” and literally anything could happen in that time. Mortal Kombat X might get a huge patch and the final DLC pack, Marvel might announce a competing fighting game that’s also on PC and DC wants to catch up, or more likely Warner Bros and NetherRealm are trying to work out whether they can release a polished experience for PC if they release that version the same day as the consoles. They haven’t technically announced a release date at all yet, and PC gets announced late all the time: Quantum Break wasn’t originally meant for PC either, yet that came out the same time on Xbox One and PC too.
