Were you at said Q&A, or are you quoting from an online source?
FWIW, Doug didn't deny that the dragon broke, or say how badly it was broken, simply that the head of the dragon hadn't broken clean off and that the dragon hadn't broken into multiple distinct pieces.
Update: Okay, IP address checks out as from inside the Disney network. I'll assume info as legit, though, to be honest, there's a lot of room for overlap between what Doug actually said and what Mr. Anonymous just wrote. There's a huge amount of internal damage one can envision to a mechanism that wouldn't necessarily require it to break apart into two or more pieces.
Also, from Doug's comments ("weeks not days") I was guessing about five weeks, though I didn't want to publish that without additional info. Given what source above is saying now, I'm going with the back half of July for the dragon's debut.
Thanks for the extra info.
