Japanese publisher Capcom announced earlier in September the coming of Monster Hunter 4, which was surprisingly revealed to be a 3DS title, and showcased some concept footage. In the latest Iwata Asks feature on Nintendo's website, game director Kaname Fujioka confirmed that the footage they showed was in fact proper gameplay footage.
In the interview, Nintendo CEO and President Satoru Iwata raised fan concerns of how Capcom were going to achieve playable versions of the scenes shown in the concept footage, to which Fujioka revealed was real-time footage of the game being played by the team. However, Fujioka was sure not to reveal any gameplay specifics.
In addition, Fujioka noted that the team had learned a lot from the development process of Monster Hunter 3G, also for the 3DS, saying that development time was relatively short, which forced the team to constantly show results of their work. They'll be applying this process to Monster Hunter 4 as they feel quite a bit of pressure. Fujioka added that if they were to develop the game like previous titles, there is a possibility that they will fail.
