when dark_b says december he means that Hobbit should been thrown to 2013. the movie cost an insane amount of money to finish the effects at 48fps in november 2012. MOS on the other side could be finished in october without a problem.
the complexity of the Hobbit effects are like 6-8 bigger compared to MOS.
