The Book Depository sent me an email 4 days ago that my order from back in October (when it was scheduled to come out at the end of October and then got delayed to April of 2014) should be dispatched soon.
I sent them an e-mail today since it was still shown as processing (impatience!) to which they replied that they "are experiencing some delays obtaining stock from our suppliers", but that they "expect to receive stock imminently"
Hopefully they'll get it sorted soon and I can finally get my grubby mitts on a copy.
