Given the amount of rumours this guy have churned out in the past, I`d say that his "sucess rate" is pretty impressive. To make a few very recent examples, he was the first to tell us about the wargulf and the blood knights. He is so well informed that even the guys at my local GW-shop use him to know what`s coming, as he usually knows it a month or two before them.
Is this "Harry" figure a GW staffer putting it out purposefully to see what we will say on our own forums? If so GREAT idea! Keep it coming "Harry," or whatever you want to call yourself.
@Infraz: I don't think stupidity will leave us. Even if we have a thousand years to cull the herd I don't think GW will give us that much
