Tony Gets Whacked at Sopranos' End: Imperioli

The Family Hour: An Oral History of The Sopranos | Hollywood | Vanity Fair:

Did Tony die at the end of the series? Some cast members

think it is quite possible.

MICHAEL IMPERIOLI (Christopher Moltisanti): I thought it was a great ending. A lot of people hated it and thought it was a cop-out, but I thought it was the proper way. Knowing David Chase, he never liked to wrap things up neatly. I never expected it to be either a cliffhanger so people would wait for the movie or wait for another season or just some like really final thing. But I think he’s dead, is what I think. David was trying to put us in the place of the last things you see before you die. You remember some little details and something catches your eye and that’s it. You don’t know the aftermath because you’re gone."
