Hey OP, my alien contact Gomabu emailed me information stating that ET first contact would happen by December 21 2012, which is 2 days after your date. This is because from that date onwards, humans would have to learn how to ascend and shift through dimensions using their spiritual bodies since the earth would have been split into multiple dimensions by then. The ascension process would basically be complete by this date. Gomabu has been right on with many of the predictions he emailed me over the past 2 years.
