I totally agree with Jeyelyahoo, adding some localisations at least for pokemons or items would be very helpful to a lot of players, including me.
We don't know how PRO is scripted, or how much time it'll take to properly implement a localisation system into the game, indeed, but I don't think it would be that hard, and I guess that JeyelYahoo (and others?) would agree.
I'm developer since more than 4 years, and bring my free contribution to this project is not something which afraid me, at all. In my opinion, it's pretty sad for you to directly refuse some help to make PRO a better game for everyone... I hope you'll reconsider such a thing!
EDIT: It seems you're using Unity for the game client, and C# for scripts, it reinforces my opinion that is wouldn't be that hard.
