I'm still on the fence because we've been told that we wouldn't get any MK characters in Injustice, that turned out to not be real.
I really hope NRS isn't just throwing out some baits while we wait for news, so far my biggests disappointments on NRS releases where:
A: Kratos over Sareena who was left out of MK9.
B: Brutalities not making the final cut.
C: Vita's Costumes being console exclusive
D: Vaguely someone on NRS saying NO MK chars on IGAU and we got Scorpion who supposedly replaced black Canary (she was in the works).
I really hope this time around is different, really, MKX has everything to be an amazing game, just don't screw it with console exclusive characters, guest characters nobody wants.
