I think Animal Crossing Mobile and even Fire Emblem will have fairly large marketing budgets now.
A few tens of millions invested now could mean billions for Nintendo in share price exploding when they can show they can make other hit mobile games, not just Pokemon. I could even see a Superbowl commercial or a big celebrity brought on board.
I also imagine the development of both of these games has been ramped up and now will be given whatever resources are necessary to ensure success.
