So any theories on the ending of Breaking Bad?

I think Walt will die in an epic Scarface ending, spraying with his M40 that he still hasn't used.

Remember when Walt and his son watched the movie and he said: 'everyone dies in this movie'? It might even be possible that Walt's family, all he ever cared for, will make the ultimate sacrifice. If everyone dies, so might Skyler. I made a bet on that: http://betsofbitco.in/item?id=1741.

So what do you guys think?
