They will sell as many as they ship. They are still vastly under the current demand in weekly shipments. I bet Japan alone could have a 300k week if Nintendo shipped 300k, with all the people that want to get Switch now that Splatoon is out.
I would assume, even if Nintendo is having a hard time with parts shortages, that they will at least be able to keep the 600-700k/month that they've been doing while still being able to hold back shipments for the holidays. So hopefully worse case scenario they make 9-10 million Switches this year. Hopefully they'll be able to up production a good amount and sell make/sell 11-12 million.
