Isn't There Only One Way Breaking Bad Can End?

Didn't watch tonight (DVR'd it), but isn't the only possibility, besides a Sopranos-like existential punt, an ending like The Shield: violence and blood and death for most everyone save one character, whether it is Walter, Skylar, or Pinkman, having to live a tortured and hopeless life ever after?  I don't know, but anything else would feel like weak sauce at this point, unless they go for the Newhart riff and bring in the cast of Malcolm in the Middle in the last 30 seconds of the series.  Still, it's only a basic cable tee vee show, so who gives a fuck?
