Xander Cage cant be in XXX3!
Xander Cage can not be in XXX 3 because they killed of his character in the second one. When they are in the NSA place after the attack and the guy asks why he cant get those assignments or something along those lines, this is a response the whole conversation is:
**NSA Agent**: Xander cage was killed in Tijuana* yesterday.
**Kyle (i believe his name was)**: Tijuana? Why can't I get assignments like that?
*The location may not be the correct one, but the lines are the same after that
