SOPRANOS the ENDING!!!!

This is why I feel Tony lived.

The second half of season 6 starts off with the ending of season 5 and in a way continues (sort of ignoring the first part of season 6).  The gun charge gets him arrested, then it goes away, then it comes back as part of a RICO predicate the Feds are using against Tony.
Carlo goes missing.  We find out he is probably giving testimony to the Grand Jury.  Tony's lawyer, who always makes Tony feel better, now is sidetracked by naked women and ketchup.
He tells Tony there is an 80 to 90% chance of inditment.  Tony is frustrated but the lawyer responds, "Trials are there to be won." Not the most reassuring comments we've come to expect from the lawyer of the seasons.

When the show ends, Tony is facing a very probable court case and at this point the Feds may have a very solid case against Tony, therefore putting him in jail for a long time.
If there had been a season 7, I bet it would have dealt with Tony facing trial. Which is something most mobsters face at some point.

All the money spent on the trial would cost the Soprano's dearly. Tony in jail would lead to a power struggle amongst his crew and probably again with New York who itself no longer has a leader (re: Phil Leotardo's death).

I feel the Soprano's had a very clear ending.  I don't think hidden clues and suggestions served any purpose other than to create tension for those final moments.
Remember people were checking their watches knowing there were X amounts of moments left.  They knew the running time of the episode before it aired.  So as they counted down the final moments suddenly it seemed as if their cable went out, which has been widely reported. 

Most people cling to Torciano, Members Only, Baccala's quote, etc. in desparation to explain what they feel.

But the script itself, the death of Phil and the 80 to 90% chance of inditment are very clear plot points that Tony survived the war with New York, but would probably be brought down in the government.
Remember he told Bobby, "Our thing people either wind up in the can or in the morgure."
Why can't people accept that Tony probably wound up in the "can"?
