I'm not excatly an expert on such shops since I'm more familiar with stores like Hobby link Japan and Hobby search.
If I remember correctly IOS was only making the doll and Dolks was the only one distributing it in Japan. It does pays to be cautious.
So far I'm rummaging through DOA to see if anything turns up. But interested parties would still have to do their own research on the company involve. Or at least email the company to see how familiar are they with this product.

Ok. so far from what I understand is that
version 2just ended their pre-order on Dolks. So this Otaku company could like one of those companies who had ordered from Dolks before hand.
Still it would do a lot more good to direct an email to them for further enquiries than speculate
