Just cause executives at Nintendo are doing their best to market this as a whole new game, doesn't mean I'm just gonna take their word and not question the validity.
At this point, there's not much more to say until we can actually play the game, and then make a proper comparison to Smash WiiU.
I just find it funny that many the same people who were die-hard about waiting several years, so that we could get a completely new and different Smash cause they were already done with Smash 4, seem to now be very lenient on what they consider new.
