Considering Switch didn't get a price cut in it's first year like most of the year 1 peakers, I really doubt Switch will fall off a cliff and sell less then in it's launch year. And falling off a cliff is almost necessary to sell less, because due to supply issues the baseline of the Switch was at least 50k below (actually closer to 70-80k, but I picked 50k to iron out the spikes) what the console sells now every week. 30 weeks worth of that gap and you already have a nice lead of over 1.5M, and considering the Smash release it's pretty clear it won't loose out during the holiday season either.
