Last time I wrote about LOKI they were expecting being able to dispatch them between March and June --> it will be rather March/April than June.
For the inpatient you could contact them for getting the puzzle without the box for a little less and asap - your decision.
I also know that they will make now an additional run for another 50 LOKIs over Easter - so the interest is obviously on the high side.
On a side matter, I could still not solve my LOKI.....
