Guys, I think the purpose of the OP posting this theory because it can't be proven until its too late to exploit it. If there is a glitch once MoP comes out that make all this level 85 gear turn to level 90, wouldn't you like to have known about it today? So in the off chance that this guy is correct, can we please cut him some slack?
And if he is wrong, so be it, but do we really need to jump down his throat?
