I think that in battles its going to be similar on when you play Colosseum with the GBA:the GBA screen shows the attacks,etc...,while the tv screen shows the animations,etc...Its going to be like that,with the touch screen showing on what attacks to choose,the hp,stats,etc..and the top screen showing the battle.While on the map,I think the top screen is going to show your character and the touch screen,will show the menu with all the options that are in the other pokemon games.It would be better,since switching pokemon,using tms would be easier and faster with the stylus.
