Tauros? Pachirisu? Ambipom? Furret? (Need I go on?)
Nah, flying types can be resistant to wind, but the same thing, I say they are not. I think wind would make a logical 2nd type for Suicune (although it may ruin his usability)
Birds that are FLY/NRM (a lot of them) can have dual typing w/wind like Swellow and Pidgeot (Noctowl should have been DRK/FLY imo)
Chimecho (spell?) spells wind.
There should be an option where we can choose a pokemon (likely from the dex) and decide on a style of sprite to view in battle and your oponent can view your favorite version of your pokemon.
Ex: You choose to view and have your oponents view the Pokemon Yellow version of Mewtwo instead of the current.
They can add new looks for the newer pokes and animation for the older pokes as well.
Another idea is having an option to interact with your friends in the free-roaming version of the game (as long as you have a connection) and the return of deep-sea diving and bases from Ruby/Saphire dammit!
