If he's doing it in an attempt to build good will with the Pokemon Company, it's a ridiculously stupid move, especially considering the amount of good will he's destroying with his fans. He's a news site and has the right to post any news he see's fit. If Nintendo were to send him a cease and desist, I could understand this behaviour.. but holding out on this for some imaginary reason? Well that just throws out any integrity I might have thought this guy had (which to be fair, wasn't much).
There's plenty of other Pokemon sites out there, most of which won't cave to pressure like this. All he's done is let us know that PokeBeach isn't a place you should visit for news.
