Character customisation is a definite yes for me, I've been wanting that for SO long. In regards to pokedex completion I would like to see a TSR (Trade Simulation Robot) in the game so that if you have a pokemon that only evolves via trade you can use the robot instead of having to trade with another person. To encourage trading between friends the TSR could cost alot of money/heart scales/shards or perhaps allowing only one trade every x amount of days, but still have the option available to people who just don't have friends that play the game. I would also like secret bases to come back because I thought they were quite fun. When you leave a pokemon at the daycare centre I think it would be neat to have a mini-game option where you can play games with them at the centre. For people who enjoy IV training I think they could introduce another mini-game that increases a particular stat by completeing certain 'training courses'. Please re-introduce the pokemon following you around because that was awesome! And please have more storage boxes so that when people want to complete the pokedex they can keep all the pokemon to show for it. Obviously a game that has all the pokemon and regions available would be fantastic, but it would require alot of memory. Perhaps on the WiiU??
