If true, this is an unforunate turn of events!
However I do not think WPM expressing himself in this manner is going to help. Rather, it can only hurt. Instead of expressing himself in a news post, WPM should use the patient application of law and kindness to alleviate any concerns he can with the (supposed) Nintendo officials who contacted him.
It's actually embarrassing for the entire Pokémon community to be represented to Nintendo (and any person outside the community) by WPM's actions. If I were Nintendo, I would take these immature actions as proof that Pokémon fans aren't mature enough to handle a more mature-oriented Pokémon game, or any larger-scale Pokémon release which have been historically Japan-only.
I am happy WPM reports news so wonderfully - I go to PokéBeach regularly, and enjoy it! But with little outbursts like this, WPM has proven he does not know how to handle himself in such situations.
