It looks like the VGZ numbers for the week of Dec 16th were adjusted for Switch. It looks like it pulled over 800k when previously listed as 730k iirc. Looking good so far. US numbers were the lowest out of the big three consoles but now it's the highest.

Yea i saw the NPD approximations and Switch won by a kinda big margin to be honest. That's really impressive considering how it will be stronger next year for sure. The console will have bundles, the word of mouth will be working its way, there was no big family title for the holidays. Mario was released 2 months from Christmas and its really far from what Nintendo can bring out for Christmas.

I think with no more stock issues in US and Japan and most likely a boost in Europe like last Nintendo consoles, the Switch can easily come close to 20 millions without forcing too much. If they have Smash, a 2D mario and animal crossing, there is no way it will not reach 20 million. 

Adjustments happening as of now...

Yes it's up to 11.9 as of December 23rd now

And likely very undertracked.

I don't know It would make sense I think. If it sells 700k during week 52 it would be at 12,6 in 10 months. We will know 3 weeks from now anyway.

I estimate Nintendo will announce 15.1 million Nintendo Switches Shipped through December 31st, and then Vgchartz will make adjustments based on how much they think were still in distribution channels (not yet sold-through).

My estimates are 1.5 million in channels and 13.6 million sold through on that date.

Vgchartz might estimate more or less in the channels at that time based on their sources, so we will see come the January 31st meeting.

13,6 would be really huge. It would easily beat the record for fastest selling console during a launch year period. 

If the current track is more or less correct, it's very likely to reach 13M units and it will most definitely outsell Wii by 31st of December.
