The Bachelorette: Alternate Endings Filmed?

With just a few days remaining until The Bachelorette season finale, speculation is still running rampant about what its star, Ali Fedotowsky, decides.
Does she choose Roberto Martinez or Chris Lambton? Does she reject both remaining suitors in what would amount to a huge emotional letdown?
Whatever the case, the show has done well keeping it under wraps. All Bachelorette spoilers we know are the same ones we've known for weeks.
Perhaps this is a testament to the greatness of Reality Steve, god among spoiler fiends for several seasons and perennial thorn in Mike Fleiss' side.
While he stands by what he says happens (follow the link above to read about it), he admits he has been stymied somewhat regarding the finale.
There's even a theory circulating that producers went so far as to film two different episodes of the After The Final Rose special as a smokescreen.
Ali Looking On
Are Ali Fedotowsky and The Bachelorette plotting a real surprise?
Ratings for the show have not exactly suffered as a result of spoilers leaking, but just the same, ABC would likely nix this occurrence if possible.
Would they really go to such lengths, though?
The lack of a single shot of the final rose ceremony in any preview to date is also strange. Could it be there is no ceremony or final rose doled out?
This theory is supported by Ali's vague comments about her tough decision, being content with what she did, etc. But it could be part of the act.
Is it possible that, just maybe, producers and Ali Fedotowsky pushed the decision back until the After The Final Rose special, which is being secretly taped this week, and no one knows the outcome because it hasn't been decided yet?
That's just our hypothesis, but longtime host and pimp Chris Harrison said that something happens on the finale "unlike anything we've seen before."
We've seen people pick no one and go home. This would be unprecedented.
