How many major exclusives does the Switch need to gain out each year to maintain popularity?

Like this year, 4 seems like a good number. Replace BoTW, Mario Kart, Splatoon and Mario Odyssey with Animal Crossing, Smash, Mario Party (hopefully back to Wii/DS levels of sales) and a 2D Mario and you're set for 2018.
