You are aware that the original SNW had three rides, right? And this will be in a new park, where they have to build a ton of rides from scratch? Not to mention that they have a ton of space to work with this time around, and the new park has to have enough to get people to come to it from the very beginning.
If we do get Pokemon and/or Zelda, no way this land opens with less than five rides. If we don't get either, no way this opens with less than four.
