Olympus just released a note on their E-M1II GetOlympus page (Click here) which says: Due to overwhelming demand new orders may not ship until January. And Olympus Japan today issued an official note to apologize for the slow shipment which is caused by the higher than expected demand. Bad news for customers but good new for Olympus :)
At Amazon (Click here) you will get the E-M1II on Christmas if you order it now.
The new E-M1II is in Stock for the first time at Adorama (Click here).
