This is crazy but it will never sell at $4000. The first auction was clearly faked and other sellers tried to follow the trend thinking they could really make 3K or more with this figure. By listing all those figures at the same time, the sellers are actually going to lower the value and make it common. You don't put so much money in a figure you see listed more than three times the same week by three different sellers. In this case, it's even 4 or 5 different sellers and figures, crazy.
Reality is, the most expensive and rarest figure of the line remains the Black & White Dark Knight Returns Toy Fair figure, which highest price is $1000-$1200. Because with time, some people may have damaged theirs or lost theirs and the figure itself is a clear variant.
Then I believe the second most expensive figure is the Black Punisher Toy Fair figure, selling for $500-$600.
Both those figures are limited to 100 copies.
Apparently this Toy Fair Ascending Batman was produced somewhere between 100 and 200 copies. It's a low number but not as low as the previous Toy Fair exclusives so it shouldn't exceed their price. Some people were able to get it through the Mezco mystery box and a friend of mine told me there was definitely more than 100 available at Toy Fair for the press.
But the figure itself hasn't been released yet, so it's hyped, but as soon as the other Ascending Knights hit the shelves, especially the MDX, which is extremely close look-wise, the Toy Fair exclusive will more than lower in value. Sellers would be pretty lucky to even get $500 for it. I don't even think that much hardcore collectors would put more than $300 into it.
That being said the figure is beautiful and I'm definitely getting the MDX variant which looks to be the best version by far. For people hunting the Toy Fair version, be patient, the value should be $500 tops, it's barely come out, it's all fresh and there are a lot of them around. Be patient and you will get it for the right price. Right now the sellers are deluded and won't get a cent out of their auctions.
