The festivities over at Capcom Summer Jam, held this year at Tokyo Big Sight in Odaiba, have revealed a release date for the upcoming Monster Hunter game coming to 3DS. Monster Hunter 4, so far only confirmed for Japan, will debut in the spring of 2013. The event also had a trailer, showcasing monsters new and old, which you can see above.
I've yet to buy a multiplayer game for 3DS, so I really hope that with some community support we'll see it come to North America. Seems unlikely though, given that Monster Hunter Tri G probably won't be coming to NA due to poor sales of Monster Hunter Wii.
