After seeing it at midnight and after thinking about the ending while at work, I came up with several conclusions. This is just a written out form so I can get my thoughts in order:
 
1) The totem did stop spinning - With this ending, everything is in order and exactly as it appears to be in chronological order. I first thought of this when he saw his children's faces and concluded that the plot progression is exactly how it should be with sense perception of something he never saw before occurring directly in front of him, with Cobb's underlying plot device of guilt done with his wife Mal, and his children. With this, it skips the Limbo time frame with Cobb and Saito and ends with him awaking normally in perfect reality, and seeing his real grandfather and children.
 
2) The totem did NOT stop spinning -  This ending concludes that he is still in LIMBO. To say that he was in LIMBO throughout the entire movie would be a misstep because of his totem functioning correctly previously in the film. Nolan could have used the, "all brain's crack" mentality and Cobb's second LIMBO run through could've been the last straw. When he leaves out of desperation to see and hold his children, Cobb loses all sense of reality because of a close attachment to what he holds dear.
 
B) If the totem could stop spinning and still have Cobb be in LIMBO, then the situation changes entirely. Notice that "Leap of Faith" as a quote is used by multiple characters, but most were in, or are still in LIMBO. Mal, Saito, and Cobb all use it but there could be others. If this were the case, then the true inception victim would not have been Fischer, but Cobb himself. In a stunning subtle twist, Cobb could have been so consumed by guilt, he possibly could have  subconsciously constructed Ariadne to confront his guilt directly and placed the idea of letting go in his head. Not only would he let go of the guilt with his wife and Mal, but with his children as well. This is the most unlikely ending because I would be completely disregarding the physics of the totem. But Cobb wasn't the only one to use the spin top, or know its effects. Another small piece of evidence would be the first scene transition from the bookend scene in the beginning with Cobb and old Saito, and the action scene with Cobb and Arthur. The building feels almost identical, giving the viewer a thought of complete LIMBO from start to finish. The mission of the Inception was the Architecture used to resolve the intimate issues in Cobb's mind.
 
As far as I know, that's about all I could come up with, but I love thinking about this movie. Anyone else have any ideas? I believe one of the most important scenes is when he sees his children. Either what he was seeing was reality because he finally got to experience his children's faces or his mind became completely lost as he deserted the totem for the sake of the dream.
