i dont belive the whole heonn region will be in it. although there could be a part of heonn or one or two major areas or cities we can reach for the legendary pokes like groudon, kyogre, and rayquaza (possibillity of sky pillar and sootpoils maybe?) but also... what about the pokemon contest??? maybe they'll hold some special major contest (if they have them) and decided to add a city or two for that... just maybe...
