VGC has the Wii's best calendar year as 2008 with 24.2m sold. Based on how most people are voting Switch is going to get very close to that, either just under it or just over it. It will definitely be interesting to see how this year's sales turn out. It could be one for the record books. (Although DS had years that were even higher.)
That would be nuts. Beating the Wii's peak year and outlegging it could bring the switch the an insane number lt. I hope it happens just for the headlines.
