If you are waiting for Animal Crossing on iOS or Android, you will have to wait a bit longer. Nintendo has officially announced that the popular sim type title will not be coming at the end of next month. Nintendo says that one of the reasons behind the delay is that they have diverted smartphone development resources to Super Mario Run for Android. Animal Crossing on mobile platforms will now be released during the next fiscal year which is anytime between April 1, 2017 and March 31, 2018. Fingers crossed we hear more soon.
More as it develops.
