UPDATE: A rep for "Sopranos" creator David Chase has released a statement claiming that Vox "misconstrued" what was said during their interview, says the Huffington Post:
A journalist for Vox misconstrued what David Chase said in their interview. To simply quote David as saying,“ Tony Soprano is not dead,” is inaccurate. There is a much larger context for that statement and as such, it is not true.
As David Chase has said numerous times on the record, “Whether Tony Soprano is alive or dead is not the point.” To continue to search for this answer is fruitless. The final scene of THE SOPRANOS raises a spiritual question that has no right or wrong answer.
