As revealed earlier today, Monster Hunter 4 is in development for the 3DS. The game is still early, and Capcom is calling the debut trailer screened at today's Nintendo 3DS Conference a "concept clip".
Here are the trailer stills Kotaku previously posted.
Even though the game is just starting its lifecycle, Nintendo's announcement that it is destined for the 3DS could impact the PS Vita. Traditionally, the Monster Hunter portable titles are on the PlayStation platform. That's changed.
