Monster Hunter 3 Ultimate allows 3DS players to rearrange the lower screen. See an example of this in the screens through the break, which also show off the portable version's impressive graphical chops.
Monster Hunter 3 has been released in about half a dozen different forms for Wii, PSP, PlayStation 3 and 3DS. This new version is coming to both 3DS and Wii U and is presumably the ultimate release before Monster Hunter 4 arrives next year.
Unusually, this one's actually going to come west (for the Wii U's launch, no less); check out the English menus.
