It turns out that today is the street date for the 2017 Wave 2 Titans Return toys, which includes Sky Shadow, Kup, Topspin, Perceptor and many others. Today, all stores importing from China simultaneously put this wave up for sale, which includes UK importer
Orbital Comics and IDToys and Japan importers
Red Mercury and Monster Japan (this is where people in Japan can get Hasbro items), to name a few. So, if any Japanese fan wants their hands on Sky Shadow (which is a Hasbro exclusive so far), they can do so today for $100. I will let you all bask in the irony that these Hasbro toys are currently out in Japan before the US.
Since these imports are from China, it only makes sense that they are out in Hong Kong, as is shown by the Titan Masters being out at
Robot Kingdom right now (the rest are currently sold out but they are taking more preorders for when they restock).
Since BBTS, TFSource and other US collector stores order from Hasbro directly rather than import, they will not be available for a while. However, Comic Shops may have these so let us know if you find em!
