That doesn't mean that's when development of the cards starts. That's when it launched. I'm designing packaging for summer 19 at my job currently. No company gets things licensed through testing and launched in 3 days. Just making sure you can register a name is a two week process.

Granted this may be different in Japan but it's not so wildly different that they're making cards in a day
