10. Sarah Connor Has A Daughter Called Jane - Terminator Genisys
The Prediction: With the new timeline which completely reboots the one audiences are familiar with, Sarah Connor's (Emilia Clarke) child who goes on to become the resistance leader isn't John (Jason Clarke), but Jane, a novel feminist twist that would write out John after he is transformed into a Terminator and becomes the movie's villain. What Actually Happened: Nothing of the sort. The film ends with it being implied that Sarah and Kyle Reese (Jai Courtney) will become lovers in the near-future, and so presumably they will still conceive John (though this is now irrelevant as John is an "exile in time", free of the usual time travel logic...because plot). It's possible that they could have a daughter in the next movie, but Genisys provides zero hints to this.
