Your assumptions are, once again, wrong. First I have wc3 experience. They belong to the same companies and so I can therefore apply the principle "entity trust" which tells me I shouldn't trust the entity. Second, though I am not a sc2 Beta tester I am close to the communities testing it such as BF forums which offer free Beta keys.
To end my statement, please note this statement is about your quote, therefore I am not assuming anything. Furthermore I would like to state that someone doesn't need to go to Blizzcon to know what's going on. Blizzcon doesn't even exist where I live, and I am sure I know people that know stuff about sc2 that we both don't even dream about.
I confess I am disappointed at your actions, I was expecting more wisdom from your part. So far the only thing I see is someone who is angry and that tries to have a revenge by throwing as many accusations as possible instead of making arguments.
I am happy you decided to take this to a demi-PM level though.
