I've got this on order atm...

The order is listed as "Still in progress", when the were listed on Amazon JP there was a note saying that some of the orders would be fulfilled by import. I guess if it has been deleted my order will be cancelled, I've got plenty of time to find out and as it stands there is no harm in leaving the order standing.
Edit: Just emailed HMV JP to see if they have any info.
