I will post few new info everyday until the 16th, for when the pokemon direct is scheduled for.

Pardon my English as it is not my first language. This is my first post here.

Today's information - It is not completely open world. After considering both the merits and de merits of it, the team decided to go with a more classical pokemon search system although the world itself will be open. I.e. You still have to walk through tall grass to get pokemon randomly.
