In an interview with 4Gamer, translated by Siliconera, Katsuhiro Harada, Tekken's chief producer, shared that the target demographic for Pokkén Tournament are people in their mid 20's.

That's not to say the game won't be something that children will enjoy as well, but they're mainly "aiming for something over 18 years of age to the early 30s" The reasoning is to bring back those who came up with the game. Harada believes that those who grew up loving Pokémon now mostly play it behind the scenes.

“When it comes to Pokémon, everyone says they love it up until the fourth grade, and what’s funny is that there are kids who graduate from it after that. Well… it’s not that they ‘graduate,’ since they’re still fans, but they just don’t show [their enthusiasm], and kind of play it more behind-the-scenes.”

Harada also knows that that does not make up the majority of Pokémon fans and that some show a greater appreciation for the games once they get older, but still wants to reach those who play Pokémon X or Y when nobody's looking.

Harada had a little more to say about the target group:

“This title is being made as an ‘adult’s Pokémon’ for that generation of people who grew up with Pokémon. Those in their 20s and 30s today have spent a lot of time during their school days with Pokémon, and have some strong memories looking back at the games and anime. And for those people, Pokkén will finally allow them to experience what it’s like to freely move around their favorite Pokémon, and I expect it to be a very impressive title. Please look forward to it.”

Pokkén Tournament is set to release as an arcade game in Japan, sometime in 2015.
