Once the Amiibo mecca was revealed to be in Hamburg, Germany (and spread out across most of Europe as our followers have noted), the cards were thrown down. Anything could happen from that moment out, and something has happened.
Someone on NeoGAF (KTS2448) found something rather interesting on Nintendo's CPSIA Certificates, Gold and Silver Mario Amiibos.
Nothing is known about these two items, absolutely nothing – except for their appearance. If there's anything we do know about these Amiibos is that if they release finding them won't be easy (unless you're in Hamburg, then it's easy). It has been revealed that certain Amibbos will have a short shelf life, making them rare in the eyes of the consumer. Amiibos have been selling out in stores across North America, so if Nintendo even hints at this release set your cot up outside your local Amiibo retailer.
