TDKR's midnight take will assuredly be higher, even without 3D. More theaters have midnight showings now,
way more than in 2008. And midnights are definitely geared toward the fans. If you can't say that TDK fanboys didn't get MORE fanboy-y in the 4 years after TDK, I'm pretty sure you can't say anything.
People who claim that TDKR can't best Avenger's MIDNIGHT take are Avenger's fanboys and don't know a thing about box office.

OW is something else, but the bit about the midnight showing, I'm willing to stand behind.
