3D Pokemon RPG. I'd like Miror B. to appear at some point because he is full of awesome, but I'd rather see traditional capturing as opposed to Snag Balls and the whole Shadow Pokemon thing and the ethics surrounding that.
And said RPG better have full trainer customization, not the half-baked system of PBR. There should also be a wi-fi battling system built in.
Also a Stadium 3 like game, but it better be separate from the aforementioned RPG... for memory limitation reasons only.
