"Pokkén Tournament (ポッ拳 POKKÉN TOURNAMENT?) is an upcoming arcade fighting game developed by Bandai Namco Entertainment, in collaboration with The Pokémon Company. The game combines gameplay elements from Bandai Namco's Tekken series with characters from the Pokémon franchise. It is planned for release in Japanese arcades in 2015, with international release plans and Nintendo exclusive console ports yet to be announced." ~wiki
So, for the arcades, there won't be joysticks like your typical arcades, but controllers like for consoles, as more people are used to them.
Not many details on the international release, but it looks promising..
I've always wanted to actually control the Pokémon!
