Do you think Pokemon Ranger will contain 4th gen. pokemon? I think it will because from what we've seen we can use pokemon without revealing to much about it besides obvious(such as a fire pokemon uses a fire attack). I think we could see the revealed ones since we saw statues of them in dungeon. Also Gamefreak is the makers of the D/P as well as Ranger so we could see some new pokemon that were previously unrevealled but, I doubt it. Although I think its obvious that munchlax and Bonsly will be in it since Munchlax has been in tons of pokemon games and Bonsly was in XD.
