World Of Warcraft: Possible WoW Hero Classes leak? Or wishful thinking?

In what appears to be one of those "my best friend's sister's boyfriend's cousin works at Blizzard and told him" posts, there is some information floating around concerning The Burning Crusade expansion containing Hero Classes.

Normally stuff like this wouldn't raise too much interest, however, SWG's big change known as the NGE was first leaked on their official forums a week before it was released.
Here is another link, in case the other one goes down. Any Blizzard Forum bannings resulting in you linking this stuff on the Official site are your own problem.
