I think what will make all the difference to Zelda sales and going forward for Switch sales is the e3 titles, plus also the directs that will continue coming.
Killer titles for me would be
Luigis mansion switch
Wave racer switch
pilotwings switch
Cruisin switch
along with new and exciting Ips !
Wait till more of the games like Arms etc and a new Animal crossing are released/announced and watch this beauty fly!!
