Tsujimoto explained that Capcom wants "to have as many people as possible play it on the 3DS, and we are only thinking about making it succeed." Tsujimoto cited a "limit to how long something can be continuously developed on the same hardware" as a reason for the switch up between Sony and Nintendo's platforms.
When he was questioned about developing for the PS4 and next-generation consoles, Tsujimoto's thoughts seemed to clash with their strategy for Monster Hunter 4: "While planning out game content, we will develop and judge which hardware is the most suitable. However, for the sake of the players, having it be a multi-development is the most ideal."
During the same interview, Tsujimoto stated that Capcom hopes to sell 2.8 million units of Monster Hunter 4 in seven months. Considering they managed to move 1.6 million copies of the Japan-exclusive Monster Hunter Tri-G for the 3DS, finding 2.8 million players to slay a fresh pack of monsters with enormous weapons might be a cakewalk.
