The two franchises announced to be coming to mobile this fall, Animal Crossing and Fire Emblem, have now been confirmed to be arriving “before the end of March, 2017” in Nintendo’s recent Press Release.
This appears to be related to today’s announcement of the Super Mario Run game that will be released on the iPhone and iPad in December.
“After the launch of Super Mario Run in December, Nintendo plans to deliver its previously announced mobile device titles in the Animal Crossing and Fire Emblem series before the end of March, 2017.”
It looks like we will be waiting a little while longer to find out what these two new apps will entail.
