I think that has to do with the weird pricing of the game and the limited cast. Had it been a full retail game - it would've been a lot more popular I feel like. Right now it's a 8 character game? Skullgirls has more characters than Killer Instinct and it's cheaper too (I believe).
Killer Instinct made me seriously consider getting the Xbox One, but then they revealed that it was basically just a small digital download title with a tiny cast. But it's still a damn good game. Justin Wong and CD Jr are tearing it up on the pro scene.
