I'd count on Chase to be unpredictable. Whether that's a good thing or not is another matter. He has been unpredictable in the past for explosive moments that paid off (Ralphie's death), and unpredictable to the point of a yawn, where he builds up tension and then erratically has it all fade with a "filler" episode unrelated to that tension.

The Sopranos, as with The Godfather saga in film, is the closest modern television can get to a King Lear-like tragedy: of a haunted, tormented soul trying to lead two lives and struggling to prevent them from colliding into one another. Something needs to happen with the Family vs family situation. Something needs to become ultra-personal. It's the only thing, I feel, which will send Tony over the edge.
