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

[fatslob-:O]

That will depend on how well the market reacts to the Switch's current lineup but so far the Switch will need at the very minimum of 2 flagships (games that will go on to sell 5M+ units in their LT) per year to maintain current demand ...

With Nintendo depleting their potential rather quickly (they already used Zelda, 3D Mario, Splatoon and not to the fullest extent Mario Kart) that leaves them with Pokemon, 2D Mario, Animal Crossing, Smash Bros and those with potential to become flagships includes Tomodachi, Luigi's Mansion along with Donkey Kong ... (Nintendo will have released 4 out of their 11 biggest current franchises for Switch in it's first year!)

With Monster Hunter and Yokai Watch not being as strong as they were, Nintendo will find themselves at an impasse with the Switch once they used all of their biggest franchises ...
