I can't help but think this is fake. I mean, there's no way on Earth they could've gotten away a literal shot-for-shot remake of it.
By that logic, there wouldn't be bootlegged figures made out of makeshift molds of official ones. They shouldn't be able to get away with this, and now that you mention it, it could also be a fake or a prank (6 months, and 20 days too late). However, there is some odd problem with international copyright law, and LOTS of these kind of rip offs get made. Just never shot for shot. Kinda like how in certain other countries, they sell bootlegged copies of our movies and sell bootlegged CD's. They're just small untraceable companies that sometimes get caught.
So... bringing that point up, if it is indeed fake, it's a very good fake for something faking something good into a bad one. Though, you gotta admit...
Animation, especially CGI, is getting cheaper and cheaper to produce
look at this ugly Alice in Wonderland trailer Still can't tell if it was a student project or an actual thing. So it really wouldn't take all that much. A few computers... you could do it out of your home.
And there is an unfortunate blind spot when it comes to Asian copyright. India (or somewhere else, I forget) has its own Spider-Man (and others... I can't remember off the top of my head) movies... very obscure, so no one can trace them. Then of course the unlicensed Hong Kong publications of certain Japanese comics (some American ones too)... there's actually a nice little coffee table book called "Hong Kong Comics" I suggest tracking down at a library or something. And I swear I saw a package of gross little fish snacks from China with Elmer Fudd on it. And he's not supposed to be.
So, the theories are it could be a fake/stunt... or it could very well be a blind spot copyright issue made by a small studio (like someone's basement) to sell in crummy stores.
