I think Savitar and emo Barry being two different versions of the future makes the most sense, definately more than the season 2 time remenant thing. And barry killing iris for his own sake would have a lot more impact than if he were to kill her out of necessity.

@Xander It's a theory. I know it isn't a fact yet.
