... but only in the USA where Toys R Us announces that it has in stock this 6863 Batwing Battle over Gotham City set, as well as UltraBuild 4528 Green Lantern and 4526 Batman sets.
These three items are listed as "In stock for shipping" and "Sold in stores ." This availability likely explains, at least in part, the appearance of the 2012 minifigures on eBay. Some employees probably couldn't resist opening a few boxes...
I cannot therefore advise you too much to follow these references on Amazon.fr where the prices and deadlines should not delay to (re) appear on the sheets of each set. I put the links below and the prices that were initially announced at the end of October.
