Why do we insist that NX has to be another PS or XB, or else it'll fail?

Also note that the release of Super Mario Run delayed their Fire Emblem and Animal Crossing mobile titles.

Would be funny if the SMR app had Mario NX ads updated into it after the NX reveal. It's all marketing ;)

SMR will be bigger title than Fire Emblem and Animal Crossing and offcourse they want to have strongest title for holiday season.
