Before Nobunaga's ambition, I was 99.9% sure that a Pokemon Ranger series for generation V will be released. however, with its birth, I think the Ranger series' chance of seeing the light of day in this generation had been significantly lessened. Since Nobunaga, I believe involves some human-pokemon interaction, and not of the core games, I believe that it is somehow the Gen V counterpart of Pokemon Ranger. I feel that releasing a new Pokemon Ranger game would feel kind of repetitive. A PMD dungeon would be far more better, but Ranger games? I am a big fan of them, but no. I think not.
