Nope, the 2nd. Which fits with Blizzards aim to launch a new hero every 3 weeks now.
But to be frank, the entire launch has been botched. The "nexuscalling" event was trite rubbish - I honestly have no idea what they thought they were doing. Invite a huge number of fans, and then have the main designers only comments on stage be "There's a map called Blackhearts Bay, you collect coins and turn them in and he destroys your opponent"?
They had 20 PCs set-up, with Khaldor and other casters there, and yet no exhibition matches?
They had numerous designers and Blizzard people there, and not a single Q&A session, or panel?
No previews of any upcoming content.
No info or roadmap about the future - instead we're relying on badly translated chinese interviews, and twitter feeds.
To top it all off, from the Youtube Johanna trailer text:
