Yah, so do I.
I'm fairly certain that the originator of the SR series was Jim Boone. Now that they have him back from Riot Games, I'm certain that they can come up with something.
EDIT : And I mean, I don't care if they break lore into a million pieces. Lore was never really SR's strong point anyway. I'll be a little disappointed, sure. But if SR5's game starts with a crawl of, "So, SR4 happened. But then the Saints found a way to go back in time and lost all contact with the Zin empire." I'd be completely fine with that.
