Us Mother fans already have the Mother 3 Fan Translation, Earthbound, and Earthbound Beginnings. We definitely need something new and I think a Remake of all 3 games for Wii U and 3DS as a physical release is a great move that will get the Mother series more popular over here. Nintendo announced a lot of RPG's in the last Nintendo Direct and I think the Mother Trilogy remake would definitely fit in. Especially because of all the fans fighting Nintendo to get the Mother games localized for Years, and I think it's finally the time since Mother 3 will turn 10 years old soon.
The Mother Trilogy definitely needs a remake, people already have the Fan Translations and Virtual Console releases so why not a Trilogy Remake?
