I think that's it: the prices are just a bit too high to bring in the sales he needs to move the stuff. Even prices on the secondary market (e.g. eBay) are dropping on "exclusives". People just aren't ready to pay more than $20/figure unless it's really special. The MOTH sets were pretty good, and they included army builders, so people seemed to buy them up. But even those figures can be found for $10-15 now.
