The only reason Capcom made Monster Hunter 4 a 3DS exclusive is the same reason they made 2 Residen Evil games like Mercemaries 3D, and is the same reason Square-Enix made a Kingdom Hearts 3DS exclusive.....3D.
As I said, a bunch of these good titles were only created in the first place because the 3DS does glasses-free 3D.
Bravely Default & Project X Zone & Code of Princess & etc. where all inspired by 3D to have their projects started, to just later end the way they did.....just look at TheatRhythm Final Fantasy, do you think that was their original intent when they said lets make a new original Fantasy as a 3D exclusive (the Sequel is called "Curtain Call" in its Subtitle), no, of course its not the original intent, but the game helps selling the Hardware from Japan to the US (but I think especially in Japan for Rhythm FF)
