20 years of this stuff and they only now shake up the formula, if Sun and Moon sells well, it will be a message to GameFreak, that changing things up is a good thing, and that they can take risks with what they do. The core concept of Pokemon will never change, and thats what draws people in, but everything around it, that can be molded, altered, edited, changed, it can be anything. And if it doesn't work? They go back to the tried and true method, which will still sell games.
The fact is, Pokemon will be around long after you or me are dead
