I'm just curious as to how the controls will be. On the PSP the analog stick is at the bottom left and the D-pad is at the top left. On the 3DS this is the opposite meaning that moving camera in-game would be a huge horrible pain in the ass, but who knows? The PSP brought out a Monster Hunter PSP that had some physical changes to it maybe Nintendo Capcom will have a Monster Hunter 3DS that has the D-Pad and analog stick switched round.
Time will tell :)
