Being that Nintendo is still making a LOT of money off of the Pokemon series of video games, I would not be surprised to see more additions onto the Pokemon series of games. I already know for a fact that there will be a new Pokemon Mystery Dungeon game coming out late this year called Pokemon: Mystery Dungeon Explorers of the Sky....but it hasn't been confirmed for release in the United States. In fact, it only just came out today in Japan. Hope this helps :)
