Unless Nintendo folds or takes over, these actions are meaningless. That is really the only controller that I have to think hard about pressing buttons.
Visually on the SNES It was presented as the right button, same as NES. Once that language went away, the bottom but has to be the primary one. All other buttons are its bitches, and the bottom button is home plate.
No other button can work in this way. The auxiliary buttons do not fan out to the left, nor are they under the Y or triangle as some secret cache of extra abilities. In summation, Sony is refusing to continue a mistake (I would support switching the symbols at the same time...), and Nintendo are fuckers.
