This is a huge achievement, and I'm sure it has been done in record time. Well done Ninty - now for the next 10m!

...

Week ending 21st October: 76,533 (-6%) 19,852,823

Week ending 28th October: 

 - sales: 83k
 - total LTD sales: 19,935k

Needs to sell more than 65k units next week (or this weekend) to hit the magic target. I would say its a certainty! 

Next stop, #1 of all time baby!

looks like it's on pace to sell infinity units in Japan.

Gah, and I still don't have one :(

awesome! now when do you guys think it will have 20M+ in Americas and Other?

It's on track to sell 60 million worldwide by the end of the year. To do this it has to sell 6 million units across the 8 busiest weeks of the year. I think it's doable. It sold approximately 7 million units the same time span last year. The odds are looking good.

Edit: on 2nd thought it will sell more than last year. More advertisement in Europe and a bigger games library will help it over the 62 million mark worldwide by the end of the year.
