There's a huge amount of confirmation bias going on with indoc theory. Anyone with an inkling of it starts looking for more clues, and start finding what they're looking for.....cause they're looking for it! Some things seem to fit...but its all circumstantial evidence on top of circumstantial evidence.
I think a FAR more likely theory is that BioWare got so damn worried about their precious Co-Op Shooting Gallery that they either ran out of time or got lazy and just pushed 3 of the same endings on us. People are giving them WAY to much credit, imo.
I also think that it's incredibly likely that the DLC will consist of little more than Shepard being knocked out by the Reaper beam just before she enters. She was never, ever, ever indoctrinated, just knocked out and dreaming the last few moments of the game. This makes MUCH, MUCH, MUCH more sense than saying our hero was too weak to resist the siren's song, particularly after all the sacrifices made.
How they choose to "end it" will be interesting. My bet is that they change little, and we get some similarly cheesy options, perhaps just as bad (or worse) as the originals.
Option One will be to somehow destroy the Reapers and have Shep walk off into the sunset in some trite and inane typical Hollywood fashion. Weak sauce, but it would appease the masses, so accustomed to such drivel. Shouts will ring out across the internets about how this is the "best ending."

Option Two may be for Shep to sacrifice herself to save the galaxy. Not certain how it would be achieved, but it's likely, and it's also a much more fitting and compelling end to an otherwise epic trilogy.
Option Three? Or Four? Who knows? Bring back the kid and let Shep push him into the Pit of Despair? Garrus does the moonwalk while Kaiden complains about everything some more? BW tells you that you can only do these options if you play 5,000 hours of the exact same map with the exact same enemies in Bored Horde mode?
Time will tell.
