Now I wouldn't mind it if the new pokemon were evolutions for existing pokemon that need evolutions for competative, (e.g. most bug pokemon, the 2 evolution normal type of all revious generations, Mr. Mime, Luvdisc, Bannette, Arbok, Weezing, Persian, Pinsir, Jynx, Farfetch'd, Sableye, Mawile and many, many more! XD)
Could also do with some more ghost pokemon too, as they are fairly limited in choice at the moment.
Also It would be nice if Nintendo could figure out a way to make tournaments, (where you can walk around, prepare, and chat with other contestants), and co-op with a friend, (game should scale itself up level wise, so that players would have to share items, or trade pokemon locally with each other to get by, or team up in double battles, (possibly 2 v 1's as well, (for a tough pokemon thats like 20 levels higher or something (this probably wouldn't work though...))).
