The answer is no, Pokemon Plus and Pokemon Minus is no longer developing due to a crooked storyline. BUT, there's a but, it WILL be replaced by a new one with exactly similar graphics and Fakemon, just a different title and story. The Gym Leaders are the same though.
Pokemon Plus and Minus would be replaced by Pokemon Titan. Pokemon Titan is based on Greece (Corin Region if you refer to my DeviantArt 'PandiRocks-17') where the map is Greece itself and the story follows the Titan and Olympian War in Greek Mythology. I would be making a thread about it sometime since I was very busy in school.
Although, I would thank you and I really appreciate you supporting me on this though. Lovelots! Also, it's kinda hard working alone, but, I would have it started in my free time. Thank you and keep updated!
