re: Breaking Bad Crackpot Theories SPOILERS

They have already made it clear that at some point there will be a very sudden move ahead several months like there was in "Gliding Over All". The gap likely comes from the time Walt leaves for New Hampshire to when the flashforwards picked up (or shortly before, while he's in NH).

Reading the episode names and brief descriptions, it sounds like Walt leaves the state in the sixth episode of this half-season, the seventh episode is at least in part centered in NH several months later and then the final episode is back in NM.
