The title really explains it all. So what would you like to see?

My list:
A game that lets you travel to all regions. This would probably would have to be on a console. I don't think they could put all 6 regions in a 3DS cartridge.
Get rid of HM moves and make them TM moves. Then have items that cut down trees,ect.
When you're the pokemon champion battle challengers. 
More stuff in the post game. I don't know what, but I want the post game to be interesting and  give me a reason to train my team to level 100.

Truth be told? I'd be happy with the Ruby/Sapphire remake that may or may not be in the works. (On the other hand, though, I don't have to PRAY for it anymore since the Ruby/Sapphire chapters of the manga are currently being printed in English, so....)

....Okay, and one more thing: Another Stadium-style Console Game. You can take most of what you used from Pokemon Battle Revolution, add online battling and just give the trainers more customization options and please, for the love of all that is good.....GET RID OF THE FREAKING ROULETTE CUP!

I would love to see another Pokemon Colosseum/XD again.
