Mostly I'm curious about what other people want to see in a pokemon game. Sure most of us want custom trainers and a G/S/C re-make, but do you want anything new in a gameplay? Or have some other request?
I always wanted a contest - like spin off, when you already start off wanting to become a coordinator, and the contest halls would be like gyms or something. It would allow contest to become more challenging and have more stages. (Heck, I don't really like contest myself, but this might be interesting).
