Ok I'll go ahead and take the heat for my comment but it's for your own good.
No, absolutely not, never gonna happen! Flame away, but by telling yourself and others it's possibly maybe or even yes you're only building a sense of hope that will be crushed if/when it doesn't happen. The Aug 20th was an earlier expected date that that more than likely didn't happen because of lack of stock. I'd stop believing in that date all together don't get yourselves wound up over nothing and then come that date be disappointed and post about how you were expecting it to be released, false hope = disappointment it'll be out Aug 31st, it's only 2 weeks just wait it out.
