We will see that =] humans are funny creatures that ask for change at the same time they hate and fear it, so we never know if they are going to change, how they will do it and if they do how people will feel and react.
You only have to look at the most popular series and see how much change they do to understand its not change that gamers what. I remember when GOD 2018 was announced and shown and how much flack it got for changing from the previous games. People who did not even play the game was all up in arms complaining why they would change up the formula. I believe if SSM wanted to they could milk the same mechanics for a while only throwing in a new weapon and some added abilities if they wanted. The thing about GOWR unlike the first game is that now your Amour and other items actually mean something as you can pretty much customize exactly how you like to play the game unlike the first.
