The Sopranos' alternate ending

The world is still reeling from Sunday night's Sopranos season finale. If you haven't watched it yet don't read any further. Reactions across the nation run the gamut. Anger, apathy, sadness, and joy are all understandable responses based on your perspective and your cinematic taste. Apparently creator and decision maker David Chase was himself torn on the ending. Over 8 diner scenes were filmed, mostly to prevent the true outcome from being leaked to the public. But was the outcome (or lack there of) what Chase had in mind all along? Some insiders say that Chase was torn between the ending that aired last night and an alternate ending.
The alternate ending reportedly begins in the same setting. Tony sits down at the diner and flips through the juke box. Instead of picking out Journey's "Don't Stop Believing" he goes with the Phil Collins classic "In the air in the night". AJ and Carmela sit down to join him. Every time a new person enters the room Tony jolts his head up. A man reading a newspaper enters the bathroom. When the crescendo lyric 'It's all been a pack of lies' hits the air the man charges out of the bathroom brandishing a 24 inch chainsaw. Several other restaurant patrons pull out concealed chainsaws and hedge trimmers. Tony squeals "What's this all about?". The leader of the group says "We're the Hackensack crew, we run this town, and we don't appreciate you laying your fat Bergen county ass on our seats." They proceed to chop AJ and Carmela into hundreds of little pieces and dump them all in the deep frier while Tony looks on in tears. Then, at gunpoint they force Tony to eat his deep fried wife and son. Meanwhile, Meadow has been trying to parallel park her car the whole time. She finally gets it just right and walks into the diner, oblivious to the hoards of bloodstained patrons filing out the front door. Just as she walks through the door a member of the Hackensaw crew pulls an 1840's war cannon out of the closet and blasts a large hole through Meadow's stomach. Tony pleads for his life, but the merciless crew only laughs. They pick him up by his legs and dump his entire body face first into the deep frier. The screen goes black as Tony's shrieks and gargles can be heard.
Just then Tony wakes up in a pool of his own sweat. "Wow that was one F----- up dream" he says. He looks over and sees Carmela sleeping peacefully. Tony runs into AJ's room and is startled to discover that AJ is just a child. He then runs into Meadow's room to find his teenage daughter typing on the computer. He asks Meadow what's day it is. She informs him that it's May 3rd, 1999. The last 8 years have all been one long vivid dream. The screen fades to black and the credits roll as Journey plays in the background.
Insiders speculate that this ending will still be used as the opening to The Sopranos movie, should it ever be made.
