Starting with Fire Emblem Heroes, Nintendo's director and president Shuntaro Furukawa said that the company is planning a major version 3.0 update to the iOS game that will arrive around the end of 2018. The president didn't divulge any more information on the update, but ensured that Nintendo will keep pouring effort into development and operation of Fire Emblem Heroes following its huge success on the iOS App Store.
According to Furukawa, Animal Crossing: Pocket Camp will also be updated in the near future, but this one will be focused on "broadening the scope of the gameplay." The iOS game is a pared-down version of the full games found on consoles like Nintendo 3DS, DS, Wii, and GameCube, and focuses on a small campsite that players can redecorate and customize to their liking, with a few other mini locations that can be visited through an in-game map.
Although details are still scarce, it sounds like Nintendo is planning to slightly expand the explorable area of the game with the update, and potentially add in new gameplay features. The company has consistently held new seasonal events and introduced new features -- like gardening -- over the past year, but its scope has largely stayed the same as when it first launched.
It's doubtful that this means Animal Crossing: Pocket Camp will see a full village for players to navigate on iPhone, since Nintendo's mobile business so far has used the strategy of introducing a smaller version of its franchises to entice people to check out the full games on console.
Because of this, it's possible that Animal Crossing: Pocket Camp's big update could align with the next mainline entry in the franchise on Switch, which is set for release in 2019. Furukawa did not detail when exactly we'll see the iOS update, but noted that "details will be announced closer to the time of the update," so it might not be until next year.
Lastly, the president confirmed that Mario Kart Tour is still on track to be released during the current fiscal year ending in March 2019. After Mario Kart Tour launches, Nintendo will have released six games on the iOS App Store: Miitomo, Super Mario Run, Fire Emblem Heroes, Animal Crossing: Pocket Camp, and Dragalia Lost.
