Now I'm pretty sure you can go into other region in this game.

This could make some interesting combos....... "Go jigglypuff! Use Shadow Claw!"

That's a pretty sneaky ability. I don't have much more to say about that.

But the airport--I have something to say about that. I'm obviously just speculating here, but:
You're able to upload your file to the internet; we learned that in a past update. Fitting every region into that little game cartridge doesn't seem feasible to me--but what if you could swap files? What if the airport is a means of saving one region file to a different storage location and downloading a different region file to your game? That would allow for players to explore every region without trying to cram all of that information on a single game cartridge.
I really don't think Nintendo would go to that length, but I'd love to be wrong. Something like what I've described above would be a win of epic proportions.

I sense that Zoroark may be put in the Uber tier because of this... But it does sound like an awesome ability!
"Magikarp used Dark Pulse!"

I really hope Zoroark isnt put in the Uber tier bc that would be a letdown to know that i cant use it in battles :/

This proves it: Zoroark will be an awesome lead. Especially if it can learn an Entry Hazard move.

Oh man I can totally see every team using zoroark as a lead. I hope people don't use it so much to the point to wear it becomes predictable. o3o
Heres to hoping zoroarks not an uber. :V

... zozoark er... whatever is gonna be a OU that everybody hates fighting...

well i have no idea at this point but by this point we will have used up all of japan meaning there will be a new nation even pokedex's hint at this:
pokedex=regeion
national pokedex=nation
next will be

The news are awesome, especially the new areas in the games, such as the airport and the theme park. The games are going to be kickass.
