Bandai Namco's Pokémon fighting game Pokkén Tournament will be hitting Japanese arcades in July 2015. No exact date is confirmed as of yet, but it has at least been narrowed down to next month.
There is still no word on a release outside of Japan, nor for a Wii U console version, but there is always a chance this will happen at some point down the line - arcade titles can release a good six to twelve months before any console version is made.
