Well, if you're looking for something official, it looks like we finally have it:
MDB228 just tweeted three hours ago:
T-Minus 1,166,400

If you convert that from seconds to days, that puts release right at August 4th.
How is that official? The original MDB228 that posted on android central said the twitter account is a sham
Perhaps they were clowning lol.
