Prediction: Kids and Marie are the only ones really innocent in all of this, thus I see them not dieing. Basically almost anyone who has had a hand in all of this is gonna die, with Walt going out at the end. He's gonna burn this mofo to the ground. Jesse wants to die, so he will get the opposite, he will live. Walt's actions from day 1, will be the undoing of his entire family. Walt will find and free Jesse. Jesse is the only family Walt has left. Jesse may become new Mike and send money to Brock. Walt isn't going to open up on Nazis with the big gun, that's too cliche. He will use his smarts to get in and kill Jack, etc. Uses rycin in a wine bottle or some gift and sends it to Gretchen and Elliot. Todd gets killed by Lydia as he gets too frisky/creepy for her or something. He gets some confused look on his face as he dies. The vacuum guy will follow through and send money to Holly/Walt Jr as they grow up or something.
Walt: Eats rycin turns himself in helps them find hanks body and dies
Jesse: Escapes and leaves, sending money randomly to Brock
Skylar: Gets killed by someone with the Nazi clan
Walt Jr: Lives with his friend
Marie: Takes care of Holly
Todd: Killed by Lydia
Lydia: Busted at the end
Jack: Killed by Walt
Gretchen: Poisoned by Walt
Elliot: Poisoned by Walt
