im still lost as to what the hell you can use a second screen for, other than generic character info and the like (though it would be nice to have an inventory screen in an rpg, and a rear view mirror would be nice, but otherwise all that I could think to use the second screen for is just health/ammo/radar/info stuff... hopefully nintendo has something bitchin)
i hope that the button layout isnt as simple as the GBA's 2-face button design
