Capcom will indeed be bringing Monster Hunter to the Nintendo Switch after much speculation the series abandoning ship with the 3DS seeing the end of the road in the near future.
Thankfully, the game will continue on Nintendo platforms, as the teaser site revealed. Currently in Japanese only, the game will be available to download hopefully in the near future. For now, we wait for a release date. Monster Hunter XX is currently only out in Japan.
