This is not a mass produced keyboard. Its designed and assembled by a single group of people. What was being "ordered" were parts which caused the delay in production. The PCB just finished production earlier this month and the keyboard will be released soon now.
The sales for this one were booked in advanced using the groupbuy system on OTD.kr. So, a group buy should not be possible. AQUA had announced that a foreign sale would probably be happening in 2012 or something. These will likely happen through eBay. To my knowledge the board is currently limited to 150 pieces, with another wave of 100 following later.
To answer some more questions from this thread:
1) The keyboard does not come with Cherry Corp keycaps, they were just used on the prototype. You are supposed to use "SoRaWeRe" keycaps with this. (Sora WYSE Replicia)
2) It uses Cherry stabilizers because they are generally the preferred type in the east
