oh after reading this guys theory, I think this makes most sense :

the ultimate architect was saito.

I think that Cobb pulled the mission off for Saito way before we see the mission take place in the movie. Saito isn't powerful enough to REALLY make the charges against Cobb drop, but he CAN hook Cobb up to a machine and create the world of Cobb's dream and make sure that Cobb goes through a bunch of things and eventually end up in limbo - thus living his "life" with his kids. It gives more reason to why Saito wanted to be there - because he was the mastermind and true architect behind it all.

how could we miss this....the end was just a recreation from his memory because his kids were wearing the same clothes and in the exact same position/doing same thing that they were always shown doing from his memory during the movie.

FACT:

1)The movie started off in Saito's limbo, then moved to Saito's dream.

2)Saito happened to magically be there to rescue Cobb from his dreamlike chase in Africa (the anonymous agents chasing him, the narrow hallway - come on people).

3)Saito was seen handling Cobb's totem (his top).

4)Saito walked in on Cobb as he was spinning his totem prior to their mission. We never saw if the top would have kept spinning or not. This is HUGE! I don't know why more people aren't talking about this.
