I have no idea, since I've never order from them and actual don't own any GG items at all. So someone else is going to have to answer that question.
Sideshow dropped the LSB and Dio lines and basically no longer have the 1/6th scale statue license for either the Hobbit (which they never had) or LOTR (which Weta now have), as such making polystone dead.
I still suspect that Sideshow have the 1/4 scale mixed media license, in other words PF's, for both the Hobbit and LOTR. It's just that so far, since an announcement some 10+ months ago for the Hobbit, not a thing has been seen. And so far, there's only vague references to seeing anything, anytime 'soon', with no new LOTR PF's shown, previewed or even teased at SDCC. More or less making the PF line on life support.
I still do expect a middle-earth PF or two to show up, maybe by the end of the year, but it must be clear to anyone, that over the past 2-3 years, as Marvel, Star Wars and DC ramp up, LOTR drops off.
The only plus side, is that unlike the Disney PF line that just died without a word, from a Middle-Earth point of view, Weta have been stepping in to fill the void.
