Having sold over 10.5 million amiibo worldwide, Nintendo are well aware of the shortages, and are trying to get more out into the marketplace as quickly as they can.
Talking to the Wall Street Journal about the shortages of amiibo, Reggie said “We are producing amiibo as quickly as we can and getting them out into the marketplace as quickly as we can. With the most recent wave, over about a 30-day period, we sold just in the U.S. over a million amiibo. Through the end of March, we’ve sold 10.5 million amiibo globally, more than two-thirds in Canada, the U.S. and Latin America.”
“There’s a huge amount of demand and that demand is even more concentrated in the Americas. It is a manufacturing process that takes some time and we had to scale up our supply chain, and it’s still scaling up to try and meet that demand.”
According to WSJ, Nintendo has confirmed that some of the harder-to-get amiibo (like Marth) will be released in limited quantities within the week.
