I have actually spoken to the people involved in this and I can confirm this is the real thing.  If you are genuinely interested  I strongly advise you to register for the event.

Satoshi believes the HBO thing was deliberately setup to draw attention away from what he is going to do.  I am about 65% in agreement with him on that point.

In any event, the above press release is absolutely genuine.  The Press Conference WILL happen.  Whether it will be successful is another issue but think about it.  So far you have heard from dozens of people saying they are NOT Satoshi.  This one is not saying that at all - quite the contrary.

If enough bitcoin and blockchain experts register, it will soon be obvious it it is not the real thing.
