im callin gail is dead for sure, because the characters who have gotten roots in the new season (mike, gus, etc) still have too much left to do on the show, i think. if they dont kill gail, (who is a kindof meaningless character, except for the fact he was going to take walts job over) it would be just fooey. they have to kill gail and walt has to continue working for gus for at least three episodes in the next season, or something.
of course this show is fucking crazy and any and all things people speculate about the show is just that.
