So most people are answering about the "new looks like discontinued" phenomenon.
I think you were asking about a product that was already active on the site and being sold for a while, and then you were assigned the last one in stock and now it's listed as discontinued.
I have never had this happen to me for an assigned review, but I know you and CherryRedHead88 have (both with Phallix toys).
Myself, if it was assigned, I would still put the review up. And I totally agree it would be sad to have to say "Sorry guys, it's wonderful but you can't have it."... but it's still worth putting the review up so people can get a full sense of what to expect from the company, I think.
The closest situation I've had to that is where I knew the Jollies Bandito was discontinued (because the manufacturer ceased operations) but there were still plenty left in stock, so I used my review to say "hey, if this interests you, put it in your cart instead of on your wishlist!"
I have bought other toys with the expectation of reviewing them only to have them be discontinued, but not on free assignment or buyout. I still plan to write a review someday, but they're way closer to the back of my "queue."
