One thing so far that doesn't seem coherent, a Bouncer already protecting a Little Sister. Even if we do not consider BioShock 2 as canon, that's early for them to be in such use. I think IG also shoe-horned that one for the sake of the final scene.

And speaking of Bio 2, there are still subtle references to it:
 * Cohen's Black Dream movie whose poster only appear in the seque.
 * Pictures of the Fontaine Futuristics building and its logo featured in a film.
 * Dionysus Park being mentioned in one of the PA ads.

That's not a lot but I'm surprised there is any, though I wouls have prefered to have at least one reference to Rapture Central Computing or The Thinker.
