If there is widespread interest in a limited collector's edition, then it usually sells out very quickly. In the case of the Treasure Trove, however, there is still no shop in which it is sold out (I lied about Amazon.fr.

It was not yet available there).
So the interest in puking unicorns either doesn't seem to be that great or the thing has been produced in enormous quantities.
