My theory(ies) as to how the sopranos ended

#1 I think Tony was arrested at the end. He was talking about how Carlo was set to testify, and right after he mentioned that, -..... cut to black. Perhaps it was the police? The FBI? And do I believe Tony was able to beat the charges? It depends... obviously, Paulie and many of the members of the family would do everything to produce a John Gotti Esque "not guilty" verdict. I also believe that Carlo could've gone Missing before the trial.

#2 I don't believe the "gangsters" that walked in were real gangsters. They were way too cartoonish. The guy in the members only jacket was probably an undercover cop. "Oooh he walked into the bathroom like in the godfather" it's like... he probably had to piss.

#3 Tony getting killed at the end isn't necessary unrealistic but I think with how insane and elaborate the show got especially near the end, it would've been too easy and expected to kill Tony. When Christopher (and especially Bobby) died, it felt extremely unexpected. When Tony killed Chris, that was shocking and unexpected, like it was supposed to be. So Tony Dying at the end- it would be like- "oh I saw that coming." Like, you give us all these unexpected things happening in the final episode especially, then why would you give us a predictable outcome like that?

#4 some people believe if Tony did die it was Paulie, Carmine Jr., Patsi, or even Phil Leotardo. (Despite the fact that he is DEADER THAN DEAD) hell, I saw someone make a case as to how Christopher came back as the Cleaver to kill him, what is this, the crow?

#5 I don't care what David Chase thinks happened Tony. The same guy who butchered the Dickie Moltisanti murder subplot in the many saints of Newark is expected to not butcher Tony?
